Babywearing Safety: "Bag" Slings

M'Liss Stelzer, author of Mothering Magazine's Babywearing Bliss how-to primer, has recently posted the results of some research she's been working on regarding safety in so-called "bag" slings*. For the full research, please create a free membership at The Baby Wearer and read "Concerns About Bag Slings".

M'Liss is a former NICU nurse, mom to two, and an avid babywearing advocate and teacher. She's married these specialties and has been doing research on oxygenation levels in newborn babies. Part of this
research is mentioned about in the Babywearing Bliss primer, but she has continued to collect data, focusing more on what she is calling "bag" slings*.

Here is an excerpt from "Concerns About Bag Slings", taken with permission from the author.

With the majority of fabric carriers it takes only a few minor adjustments to get baby safely and comfortably positioned (see the "Correct Positioning article")". However, unlike most other types of carriers, it appears the Infantino SlingRider baby carrier has several significant design flaws that could place an infant at risk of respiratory distress, oxygen deprivation or even suffocation.

First
, the design of the SlingRider causes baby to naturally curl chin to chest, larger babies more so because their heads are positioned further up in the carrier. This position kinks baby’s airway causing the baby to work harder to breathe. (For more information on the importance of maintaining an infant's head and neck in an aligned position see the articles “Baby car seat ‘cot death’ concerns” and “Simple Car Seat Insert to Prevent Upper Airway Narrowing”.)
Now, the instructions for every Infantino front pack emphasize that baby should
not be chin to chest (“Baby's chin should not point down toward baby's chest") and there are even diagrams of correct positioning. However, the SlingRider instructions omit this important detail and, not only that, but the product shots of the SlingRider contradict the information in the front pack instructions.

Second
, it is very difficult to keep a newborn’s face away from the pouch fabric. The SlingRider is roughly triangle shaped; flat bottom and two sides that slant upwards toward the elastic top. This “triangle” means that the pouch fabric is always angled very close to the sides of baby’s face. If baby rotates even slightly he ends up with his nose within a ¼” of the side, or even pressed against the side of the pouch. Once baby has his head pressed against the side of the carrier and/or against the parent's body there is a risk of the baby suffocating or becoming oxygen deprived. (See SlingRider #1)




Third
, it is very difficult for the parent to monitor their infant unless they pull
open the top of the sling. The SlingRider is deep, plus it sags when baby is placed in it, further increasing the depth of the carrier. The gathered top and the fact that the sling hangs so low obstructs the parent’s view of baby. If a newborn were to have difficulty breathing, and/or rotate until his nose and mouth was pressed against the side of the carrier, the parent may not be aware of the baby’s respiratory distress for some time. Compounding this problem is the impossibility of feeling the baby's distress through the thick fabric of the sling.

Compare the SlingRider with a shallow fabric pouch or adjustable open-tailed sling (or mei tai or wrap). In these types of carriers an infant is easily monitored and visualized. Also, a newborn's head is effectively sandwiched between the sides of these carriers, preventing the infant from rotating his/her head into the sides of the carrier.




Disclaimer: Although M'Liss has only been able to test babies in the SlingRider (because that's the only bag sling she has in her possession) she want parents to know that other bag slings probably present similar dangers.


*bag slings
"I believe there are two significant features that distinguish the dangerous "bag sling" from a typical pouch.

First: The bag sling has a padded, structured bottom (in the area where the baby's body rests). Therefore the fabric that supports the baby cannot conform to the baby's body and it is almost impossible to position the baby diagonally across the fabric, for proper back and
head support. (Also, if the "safety harness" is used, it
forces the baby into an improper parallel-to-rails position.) The padding also makes it nearly impossible to carry the baby snug against the wearer's body, because it creates a flat surface that resists being adjusted and tightened.

Second: The rails are padded and elasticized, so -- esp. in combination with the depth of the pouch -- the sides of the sling tend to "close up" over the baby, restricting the flow of fresh air, and preventing the wearer from being able to easily see and monitor her baby. (This is less of a problem with an older baby who is sitting more upright in the sling, of course.)


The third big difference between a "bag sling" and a regular pouch is one more of wearing comfort than of the baby's safety, and has to do with the difficult-to-adjust heavily padded strap that goes over the wearer's shoulder and back. By itself I don't think this is a major
safety issue, but in combination with the above features, it adds to the tendency of these slings to be too large and very difficult, if not impossible, to wear snugly and with the baby well positioned.


So, the problem is more or less a function of the way you put the baby in the sling, but the
issue with these bag slings is that, by their design, they encourage poor positioning."

Babywearing may be over but the baby carriers are still needed!

My beautiful Maine Coon cat died in late December after a long and wonderful life. A perfect 17 year friendship! I guess I moped a fair bit because my family is thrilled to see me smiling again.

Why?

We got a new kitten! We are all in love.

Oh.

Oops. Not all of us are in love, actually.

Our two year old kitty is purty darned pissed, actually. We brought the new kitten home yesterday and she was, ah, rather rude. I have never seen her make such distasteful faces, and the things she said? Well I am not going to put them up and risk offending you. Most unbecoming! Well anyway, we are all taking turns to try to keep the little guy safe and help our old grouch to remember we still love her.

I found myself holding the adorable little baby in one hand while lifting storage bins with the other. He was being stalked. She's already clocked him good a few times and left his head spinning.

It dawned on me that there was something familiar about this situation. I was needing both hands but one hand was busy holding this sweet little kitten. What to do? What to do? Oh yeah! That's right! A baby carrier! Well, okay, Stacey of Karma Baby did ask me to take some photos of my new baby in a pouch but I didn't realized it would be a safety thing to have him in there!

He loved it! Looking down from on high while safe and warm was a relief for a little while, anyway. Of course, he's still a cat, and a little one at that. So curiosity got the better of him and down into the fray he went. Quick! Off to give some huge cuddles to our old grump!
