My almost 5 month old son is rolling over from tummy to back. He’s a tummy sleeper & does it in his sleep when he’s starting to stir between sleep cycles. So instead of transitioning through the cycles for a 2 hour nap, he’s waking up after 40 min, talking & fussing. When I walk in to help him go back down, he’s smiling & talking to me. Then he refuses to go back to sleep. Other than WTS, does any one have any suggestions to help with this?
