Tummy Sleeping 😬

My son is 4 months today. He started consistently rolling from back to belly two weeks ago. The problem is, he isn’t great at getting from his belly back onto his back. He usually fusses until I roll him back over.

At night a couple of times I’ve woken up and he’s sleeping literally face down on his belly. I always go in and turn him over but it scare the shit out of me!

There’s really no way I can stop him from rolling over at night, so what should I do? Is he old enough to just let him sleep how he wants? I’ve been staying up way too much just staring at the monitor lately 😓
