Re: 4 year old getting out of the room
My kids are the same. My oldest is known for waking and coming in to our room. I take him back to bed and sit with him for a couple minutes until he falls asleep. He's been waking b/c now that he is potty trained, when he has to go pee, it wakes him up and then he wanders. I wouldn't worry too much about a sleeping disorder. Not every child who has sleeping issues (staying asleep) has anything medically wrong with them. If that was the case, we would be at the doc's every day! If you think your child has something wrong see a doc, otherwise, I tried putting him to bed earlier (7pm) and it has worked wonders. If he does get out of bed, it's still early enough where I can get him right back to sleep at a decent hour. Good luck!!!
