My son is 4, and he gets up every night to go to the bathroom. When he goes back to bed, he has trouble falling back asleep and will either talk, sing or play until he does and that sometimes takes hours. I'm glad he knows when to get up to go to the bathroom and doesn't wet the bed, but I am worried he is not getting enough sleep. It has started to effect his behavior during the day and this has now been going on for weeks. Does anyone have some suggestions on how i can help him get back to sleep better?
