I lay by girl on her front. She’s 10 months and can roll herself both ways. If I lay her on her back she is awake for longer fussing and then rolls herself over eventually to sleep, I just put her straight on her tummy now as she will go straight to sleep without fuss and sleeps through till morning
I have always put mine on her side, it was the only way she would settle due to reflux. She flip flops from belly to back all night long, which is quite annoying as we cosleep. She does do longer stretches if she’s on her belly.
They sleep better on their stomach (as do adults) because pressure on their stomach calms their nervous system. Their airways are also technically more open so they take longer slower breaths and therefore burn fewer calories...ergo wake up less to eat. That being said, it's also a risk of breathing in more carbon monoxide because there is less air flow in front of their face causing an increased risk of SIDS. So do what you will with that information!
My little ones both ended up being tummy sleepers well before their first bdays. I would say they are safe since you stated they can roll both ways just rarely does so on their own. I’d give it a go for a few nights and let us know how it goes for you, momma! Crossed my fingers for you!
Exactly the same here - hates tummy time, sleeps through the night on her front 😅 she came to it naturally by herself though so I didn't worry as I've always taken my cue from her
