why do babies like to sleep with their butts in the air?

Just curious. Dd2 (10 months old) prefers sleeping on her tummy, with her knees underneath her and her butt WAY up in the air. I think it's very cute, and I remember ddd1 doing the same thing as a baby/toddler. Any thoughts on why babies/toddlers do this? It doesn't look very comfortable.

I remember sleeping like that as a small child. I still find it kind of comfy, although less so because I've lost so much flexibility. Try it yourself and imagine it without the muscle pulling sensations, it's not bad

I don't know why either, but I know I did it (one of my dad's favorite memories of me) and my 26 month old still does it too!
And I've noticed when she sleeps in that position she is really OUT, it is a hard sleep.

Ahh...that makes sense. When she is sleeping on her side, she puts her legs in the same position. Even curled up next to me, she is...well, curled up.

We put her down to sleep, and then a couple of hours later I join her (we cosleep). She sleeps that way until I climb into bed, then she mashes herself against me for the night.

airway issue

this is a very common sleeping position in children who have an airway restriction (usually tonsils or adenoids). the reason they sleep this way is that it helps open their airway, which allows them better oxygenation during sleep. in many areas in the US, the pollution or pollen causes kids to have swelling in the tonsils and adenoids, which leads to partial or complete blockage of the airway when they achieve phase III sleep (where neural development and long term memory occur). Kids do not usually experience sleep apnea, but go through what is called sleep disordered breathing. This means that as they drift into phase III sleep, the muscles in the neck, jaw, and tongue relax, causing a restriction in airflow if the tonsils and adenoids are in the way. This then leads to decreased oxygen flow which causes the 'fight or flight' response, leading to a burst of adrenaline moving them back into phase II sleep. This occurs over and over throughout the night, leading to poor sleeping habits, orthodontic malocclusion, and ADHD. I would have an ENT take a lateral skull xray (face positioned perpendicular to xray film) / lateral cephalometric xray (usually taken by a pediatric dentist or orthodontist) to evaluate the adenoids and tonsils. Just because they sleep like this doesn't mean they have an airway issue, but I would want to rule it out if it were my child.
