I need help!! My 3 month old will not stop rolling from his back to his tummy while he’s sleeping. I keep waking up or staying awake to make sure he’s not sleeping like that for long periods of time and so I can flip him back. I know it’s not safe, but what can I do? Any experience with this? When can I start letting him sleep like that? We have a pediatrics appointment next month for his 4 month check up, I will ask pediatrician about it then too.
