Hi, I need some advice! One of my twins (5 months old, 3.5 months adjusted age) has just learned how to roll over onto his tummy and now he is rolling over at night in the crib. Then spends some time pushing up and kicking (definitely playing, not sleeping), and then he vomits (he has mild reflux) and cries, and then I have to go clean him up. He definitely does know how to roll back onto his back, but he doesn't do it at night, even after he throws up. So I go clean him up and put him on his back drowsy but awake, and he immediately rolls over again as soon as I leave. Over and over. I ended up moving him to the bouncy chair last night after 2 hours of this. The pediatrician says to let him stay on his tummy if he rolls over on his own, but even when he is making himself throw up? What to do?
