So, I never ever post here anymore. But I'd like to have my oooold entries for posterity, and then delete my account because I'm not particularly comfortable with the new LJ owner situation. All the backup tools on http://www.archiveteam.org/index.php?title=LiveJournal are nonfunctional. Does anyone have a good tool? Should I go to Dreamwidth or whatever that was called? What are you guys doing?

Also, hello! :)

I wrote this up today, after hearing M'Liss Stelzer at the 2010 Babywearing Conference in Rigby. She shared a lot of great information, most of which is included below, but while I wait for her to put it on a website, I thought I'd get it out any way I could, too. It pertains not just to baby carriers, but every device you put a baby in, including car seats, strollers, bouncy seats, and swings, so please pass it on to anyone you know who is pregnant, planning on having kids, or has a newborn now. It's really important stuff! (This is copied from my site at http://www.sleepingbaby.net/carseats.php and is available as a PDF at http://www.sleepingbaby.net/infantsafety.pdf if you want to print it out or send it via email.)

Newborn and infant safety

Key points:

  • Car seats are for use to secure an infant when riding in a car. They are less safe than a baby carrier when used outside their intended purpose as car safety devices.
  • Infants are safer in their caregivers' arms than left in a device (car seat, stroller, bouncy seat, crib, swing, etc.).
  • Carriers that offer correct positioning are far safer than ones that promote incorrect positioning (i.e. forcing the baby's chin to his chest or awkward reclining holds).
  • It is vital that caregivers be aware of their infant's breathing at all times.
  • It's okay to wake the baby to take him out of the car seat. Deep sleep is a dangerous time for infants; SIDS invariably occurs during deep sleep, and other breathing difficulties are also a greater risk during deep sleep.
  • Infants should always be visible and kissable in a carrier.
  • Any carrier should hold the baby the way you would hold the baby in arms.
In the last 15 years, much has been learned about keeping newborns and infants under 4 months safe. The “back to sleep” campaign is responsible for a considerable reduction in SIDS and related deaths, for example. However, there is a great deal of research into infant physiology that still has not filtered into either popular knowledge or product design.

In 1995, a study was done on infants’ oxygenation levels in their car seats. Normal oxygenation levels – that is, the amount of oxygen circulating in the blood stream attached to red blood cells – range between 97-99% in a healthy term infant in optimal positioning. Any oxygenation level below about 90% is considered “hypoxia” – the baby is not receiving enough oxygen, and brain damage can result if that level is sustained. Shockingly, healthy, full-term newborns placed in correctly positioned car seats had oxygen levels that went as low as 83.7%. In the hospital, such levels would bring teams of nurses scrambling to the infant’s rescue. While not all infants’ oxygenation levels reached such depths, there was a consistent finding that the longer the baby spent in the car seat, the lower their oxygen levels would go, until thebaby was removed from the seat.

The study was repeated in 2005, with the same results. The conclusion in both studies was that babies should spend the least amount of time possible in a car seat, and they recommended that car trips with new babies be kept to an hour or less, and that infant car seats be used only in the car, and not beyond that.  And yet, these studies and others like them have gone almost completely unnoticed in the United States and Canada, and it’s not uncommon to see infants in car seats for hours on end, being moved from the car to a travel system to home without ever being removed from the seat. How much damage is being done to these infants while they seem to sleep so peacefully?

Hypoxia is known to cause damage to the developing brain. Infants who experience hypoxia will show more signs of ADHD, decreased IQ, delayed motor development, and impaired attention. If these conditions sound familiar, perhaps we are beginning to understand why, as more and more children spend their infancies in some form of baby seat, reclined and in a hypoxic state.

In addition to the hypoxia seen in healthy, full-term newborns, there is also a risk due to positional asphyxia. This unfortunately is not an uncommon cause of death in infant car seats. A newborn baby’s head is very heavy, and its neck is quite fragile in comparison. Newborns, especially but not exclusively those born prematurely or with respiratory issues, are prone to having their heads tip forward onto their chests, drastically narrowing the airway (which is about the width of a drinking straw) and blocking proper flow of air. This can cause hypoxia and even death, and is a risk in any baby containment device that places the infant in a seated position, including (but not limited to) car seats, baby swings, bouncy seats, and yes, even cloth slings, if the parent doesn’t follow positioning guidelines.

So, what do we do about this?

Knowledge is key.

Every parent and caregiver *must* be aware of their baby’s position and breathing at all times.  Let me repeat that. Every parent and caregiver must be aware of their baby’s position and breathing at all times.  Whether the baby is in a car seat, a sling, or even in the caregiver’s arms, he or she must keep an eye on the baby’s respiration and positioning. (This does mean that if you have a newborn and you must take a long car trip, it is best for one caregiver to sit in the back with the baby whenever possible, and stop frequently to allow the baby to recover from hypoxic episodes, which grow more severe and numerous the longer the infant is in the seat.)

In a carrier, an upright, chest-to-chest position is best with newborns and infants under 4 months. In this position, the baby is aware of the caregiver's breathing patterns and vice-versa. (Human infants are programmed to take breathing cues from their parents, and often an abnormal breathing pattern is noticed subconsciously by the parent, who then rubs the baby's back, bounces, or sways, all of which will help reorganize the baby's breathing.) The caregiver is able to keep the infant's head in an optimal position, usually turned to one side, and this position is one that adults often adopt when holding a newborn without a carrier -- always a good sign that the position is a physiologically healthy one.

When a carrier is used to recline an infant in what we consider a cradle hold, it is vitally important that the baby's head still be in easy view of the parent, and close enough to kiss. The baby's neck should be straight down to his pelvis, and while it is okay for the spine and legs to curve gently (because infants are naturally curled up), it should never be at a more extreme angle than one would see with the baby held in arms. In any carrier, a good test of whether it is correctly positioned is to bring one's arms up around the carrier as though it weren't there. If there is significant movement, then the carrier needs to be adjusted so that they mimic an in-arms position as much as possible.

It should be clear by now that "bag sling" style carriers (those with a hard bottom, and curved and elasticized tops) are never a good choice for carrying a newborn. The flat bottom tends to allow the infant to roll towards the parent (with or without an internal harness), creating a risk of suffocation, while the shape of the carrier forces the infant's head onto his chest. In addition, the closed top keeps the baby from being seen, so that if hypoxia does occur, the parent misses the signs, often until it's too late, and because the baby is so deep in the carrier, he is also at an increased risk of rebreathing carbon dioxide. The "bag sling" is really a perfect storm of hypoxia causes, and it should come as no surprise that the majority of "sling" deaths have occurred in this style of carrier.

Other safety considerations in baby carriers:

Any item that is made of fabric and that is used regularly is going to wear out some day, whether it's a favorite toy, blankie, cloth diaper, or carrier. This is also true of cloth baby carriers; there is no magic in a fabric when it's made into a carrier that keeps it from wearing out with use. All fabrics take a beating when they are weight-bearing, and when they are washed and dried repeatedly, the fibers will start to break down with time. For thick and sturdy fabrics, this may take years of heavy use, but for fabrics that are appropriate for slings and wraps, it make take less time, because the fiber threads tend to be thinner.

When using a sling, whether it's brand-new or a hand-me-down, please be sure to look over the entire length on a regular basis (such as after it's been washed and dried, or before you thread or put it on) to check for weak spots in the fabric. This would include areas where the fabric is pilly, where the surface appears fuzzy, or where you can see broken threads in the weave. Any carrier that has holes in it should be used with extreme caution, or preferably not at all, since a hole can easily develop into a full-blown tear with stress (such as when the sling is adjusted through the rings, or when a wrap is tightened). A well-loved carrier often has a lot of sentimental value, but it's better to use it for a blanket or child's lovie than to continue using it as a carrier after it shows signs of wear.


It is not my intention in sharing this information to terrify parents. We do have enough to worry about as it is. However, the media seems very quick to jump on baby slings as the hazard of the week, while ignoring the very real hazards of leaving infants in their car seats and other such devices. The studies on infant car seats and hypoxia (below) all come to the same conclusion: leave the car seat in the car. While manufacturers have made it easier than ever to go through a whole day with the baby in the car seat (including travel systems and snap-on stroller bases), they are not doing so based on the available research (and why should they, when it would hurt their bottom line?).

Parents often assume that since a baby product is sold in a store, it must have been tested, but that really isn't true. Some products are, but the vast majority are not, as can easily be seen by the number of recalls that occur each year. Consider the number of cribs that are recalled each year, including finally the whole drop-side crib category. Had they been rigorously tested, the recalls never would have been necessary, but infant products, like most others, are primarily "tested" by the public after they are released. There have been far, far more deaths in car seats, bath seats (the number one in terms of infant deaths per unit used), strollers, cribs, bouncers, and swings than in slings and other carriers, but you'd never know it from the way they were marketed and reported on.

Finally, a little fear can be healthy at times. Infants are on the whole remarkably resiliant (there are nearly seven billion of us on the planet, after all), but physiologically, we were not made to lie in plastic containers all day. Human infants thrive on touch, motion, and closeness with their caregivers, and it would be misleading to say that being held is "beneficial" to babies and their caregivers: it is simply what we are wired to do, and anything else is actually detrimental. A good baby carrier allows caregivers to fulfill their babies' needs and still go about their daily tasks with ease, and that is the real benefit.


This article would not have been possible without M'Liss Stelzer, RN, who brought these issues to the attention of the babywearing world way back in 2006. Her presentation at the 2010 International Babywearing Conference was excellent, and I hope to see it online soon. Until then, I wanted to make sure the information was out there in some form, and she inspired me to write this and see how widely it can be disseminated.

I'd love to pick up a copy of "The Folklore of Discworld", but it's available only in the UK, and Amazon.com in the US wants $70 for it! Would any of my UK friends be interested in sending a copy to me? I can pay you by PayPal, or by credit card on the amazon.co.uk site, have it shipped to you and then pay you to ship it to me, whatever works best :) (I'd love to pick up the Streets of Ankh-Morpork as well.)

Wish TP was more popular in the US, or at least that the US publishers would pick up all his stuff.

ETA: Thanks, everyone! I got a reply via Facebook, so yay!

I just got the *worst* push-poll I've ever heard. It was from "CPRAction", funded by NOM (National Organization for Marriage), and it made me *so* angry! They introduce the call with the note about the NH senate approving same-sex marriageThey ask (robocall): "Do you agree that marriage between only one man and one woman should be legal?"

Which, of course, sounds like you're being asked if heterosexual marriage should be legal. Well, duh. Why not?

But I couldn't just say yes, because they want their poll to say "99% of respondents believe that only heterosexual marriage should be legal!"

So I said "That's a very poorly worded question."

And the robot said "You must answer yes or no."

So I said "No."

Then it asked if I'd donated to a campaign, church, religious organization, or other non-profit groups. Well, I have -- quite a lot of the first and last categories, actually -- so I said yes.

And then it asked for demographics. "Are you male?" (Because that's the default, of course.) "No." "Are you above the age of 50?" "No." "This concludes our call. This poll has been funded by CPR Action and the National Organization for Marriage."

I yelled, "You suck!!" into the receiver but there was no human to hear me.

Damned robots. Damned NOM. How twisted is this so-called "poll" going to turn out, the way they've worded it?

At this rate, I may finish by Valentine's day. Though I haven't knit a stitch today. It's already almost as tall as David!

I knew it had been almost a year since we officially fell in love with this house, but I didn't realize it was more than a year already. Looking at last year's entries, it appears we put an offer on it on 1 February, 2008. What a rollercoaster that was! I'm really happy with the house, though, despite the moldy basement and its other little quirks.

For whatever reason, David keeps looking at NNEREN and pointed this one out to me yesterday: http://www.nneren.com/view2.php?id=2735688&ref=r&price=$319,000.00&t=&fcla=
Is that not completely gorgeous? And we could have swung it, too. A pity it's a year too late! Then again, the listing says "...the home invites its new owners to return it to its original splendor" which to me says, "Get yourself a Home Depot account, because you're gonna need it!" Still, wow.

I seriously need to go back and tag those entries. And make a house icon. It's been a year, after all.

Hurray! The commission has added a one year stay of execution on the CPSIA -- the provisions are still in effect, but testing is not mandatory on most items. So we're in the clear until Feb 10, 2010, by which time the guidelines should be much clearer and based in actual science, instead of scaremongering.

Thank you to everyone who wrote and called the CPSC and their representatives -- I really think that made all the difference.

2008 Consumer Product Safety Improvement Act

Everyone wants safer toys and other items for their kids -- there's no question of that. So in 2008, Congress approved the Consumer Product Safety Improvement Act, a sweeping reform of current safety legislation. Sounds great, right? Now our kids can be protected from lead and phthalates in numerous products, and who on earth would vote against that?

Well, the trouble is the broad scope of the legislation. It doesn't target only plastic or lead-painted toys from China. It targets every single item made and sold in the United States that will be used on or around children. Whether you're a giant corporation importing toys, or a tiny garage business making wooden toys, or, like me, a mom sewing slings to help pay her mortgage, everything has to be tested. Testing for lead costs more than $100 per item. And this means, every fabric, every color, every different color of ring, has to be tested for lead. For me, that means a conservative estimate of $8000, based on my current fabric inventory (add another $2000+ if I add more colors or fabrics in the future, which I will need to do eventually). I would also need to test zippers and snaps -- each different color -- so I would be looking at around $10,000 (minimum) in testing. That's a huge portion of my annual profits.

Obviously, that is totally unsustainable for a small business, or even a big one. My business, along with pretty much every single other cottage industry, would be forced to close down, or face fines of $100,000 and even jail time for violating this law.

This goes for other textile items as well... including knit hats, blankets, cloth diapers, stuffed animals and other plush, and boutique clothing. *Every* WAHM producing anything of that nature will be affected by the law. Keep in mind that lead levels in fabric are already low -- on the order of <10ppm. The standards right now are 900ppm, falling to 90ppm in the future. Even at that level, the vast majority of fabrics would pass... but the act doesn't specify that fabrics are exempt.

The economic impacts this law has on business in America cannot be understated. One gentleman has gone so far as to dub the day the testing provisions go into effect (Feb 10, 2009) "National Bankruptcy Day", because any business that hasn't tested its products will be unable to even liquidate its inventory (since untested products are assumed to be full of lead and thus hazardous), leading to mass bankruptcies. That's NOT what our already-shrinking economy needs right now.

The law was well-intentioned, to keep children from getting sick and dying from lead poisoning. But it ignores the fact that the vast majority of lead-tainted products were from large manufacturers, almost universally imported from Asia, and instead puts this impossible testing standard squarely on the backs of small American businesses, the very ones that Americans *want* to shop with right now for their record of safety and honesty. What this act will end up doing is making it impossible for small businesses to compete (since the costs of testing will have to be passed on to consumers, and small businesses will pay disproportionately compared to big ones), and limiting the choices Americans have in their shopping.

These sites offer more information:
If you value small businesses and handmade products, I urge you to contact your representatives, sign the petition above, and email the CPSC and let them know that this act is *not* what you want. Handmade products are historically far safer than imported, mass-produced ones, yet the latter will be all that is left in the marketplace if the act goes into effect as written.

I got my first email account in 1992 -- it required a computer science major to help me set it up, since all the settings were manual. When emailing, I had to type in a lot of the stuff that's now behind-the-scenes.

1992, 17 years ago, was half of my life ago.

Ooooh, this stuff is *wonderful*! I got the "comfy" yarn, a 75% pima cotton, 25% acrylic blend, and it feels soooo nice to the touch -- very silky. I'm going to enjoy knitting with it, I think. The materials (well, plus a pair of circular needles because they were pretty and bumped me up to free shipping) were $51.63. A lot for a scarf, but since it's for my honey, it's okay :)


Will try to photoblog this as I progress, just for the hell of it.

Okay, the universe wants me to make David a Dr. Who scarf.

I was reading my Google Reader feeds and clicked on a pattern for a neat looking scarf. While I was checking it out, David glanced over and said, "Oh! Could you make me a Dr. Who scarf?"

So I googled it and found www.doctorwhoscarf.com (who knew?) and spent about 10 minutes checking it out before going back to Google Reader. Read a few more articles, scrolled down... and there was this.

So, clearly, I am meant to make this scarf.

However, I'm not sure quite how. I mean, I have the directions (he wants the season 15 version), but I'm not sure about the yarn. Wool makes me itch, and him, too, so I'm stuck with non-woollen yarns. The directions call for a sport or DK weight yarn, and I would prefer to use something that feels nicer than the cheapo "pound of yarn" crap (I hate that stuff). OTOH, it's a *crapload* of yarn, and I don't want to pay more than, oh, say, $50 for the yarn. I can't tell exactly from the pattern, but it looks like I need between 200 and 400 yards each of 7 colors.  Of course, the pattern calls for it to be between 10-12" wide, and David wants something about half that width (and maybe shorter, once he sees how very long it is), so I guess I don't need quite as much.

Knitters, do you have recommendations for nice-feeling but not bank-breaking yarns? I like working with soft but not too stretchy yarns; have had success with a lovely chenille I got at my LYS, but it was years ago and I don't remember what it was called.
