My 4 yr old has begun getting out of bed in the middle of the night and either coming into our room, or going into the room of one of his brothers or sisters and sleeping there. This seemed to begin around the time he became potty trained. We hadn't had any problems with him staying in his room prior to that. We have him use the potty before bed, have tried limiting drinks for a certain amount of time before bed, have tried incentives for staying in be all night....nothing is working. He used to only come into our room and try to sleep with us. I always get up, have him potty, and take him back to his own room. The problem is, once he discovered that we won't let him stay in our room, he began going to someone else's room instead. So we don't usually know until the morning. The other kids are too out of it during the night to know to come and tell us or take him back to his room. We are at a loss for what to do.
