I let my baby sleep on his stomach now, he’s also 7 months old. If he can I’ll onto his tummy then he has the head control to be fine in that position. Also I taught my baby how to roll from his tummy to his back by playing with him on the floor doing the movement until he just started doing it himself.
My daughters started at 5 months old. And I let them sleep like that. Of course my anxiety was high but my pediatrician reassured me that it is normal development and nothing to worry about. If you are still swaddling it now time to stop. You don’t have to roll baby back over. It’s considered completely safe for baby to sleep that way especially if they are rolling themselves into that position.
I let my baby. He has done this since 5 months and sleeps so much more content. X
My daughter also preferred belly sleeping once she started rolling. Initially I rolled her back, but we just leave her now and she is fine.
