My 5 year old goes to the bathroom every night before bed. I do not allow her to drink after 6, but a few hours after she falls asleep she will sometimes wake up crying. She will cry while going to the bathroom and then back to bed. She doesn't talk to me or anything. Just walks in and walks out and goes back to sleep. All the time crying. I'm not sure why and was wondering if anyone else's child does this. I don't know if it's nightmares, but when I ask, she says she didn't have a bad dream. So i don't know what it could be.
