Anyone else? Just my baby? Ok

So my baby has not mastered rolling yet. He has rolled from his belly to his back several times but it's not consistent, and can roll from his back to his side. He LOVES being on his side. He plays and prefers sleeping on his side. The problem is, I will put him down to sleep at night on his back and he will roll onto his side immediately, which ok fine. I heard if they can do it themselves then it is fine. But the problem is, while he is sleeping he falls back onto his back, gets startled and it wakes him up crying and upset. Every. Time. And then he can't go back to sleep so I have to get up, soothe him and as soon as i put him down, he rolls back onto his side.

The cycle just repeats 😭. It's exhausting at night!! Any Tips? Anyone else's baby doing this?
