I don't know what's going on with my son's sleep. He's been sleeping through the night perfectly well for months. There have been ups and downs here and there because of teething, milestones, etc. In those instances though it's only been a night on and off until whatever is going on had been resolved.

For the past week he has been waking up once or twice between 3 and 5. Instead of just putting himself back to sleep (like he had been doing) he screams as if he's in pain until DH or I goes into his room. Once we're in there he's fine. He'll even be happy if we sit next to his crib within touching distance. If he can hold my hand/stroke my arm he's happy even though he is still wide awake. As soon as we try to leave he freaks out completely. We can't even sit in the corner of the room in the glider because we're out of touching distance.

Last night he was awake from 3-5am, laying in his crib with one of us sitting next to his crib. Does he just miss us? I just want to know what the problem is. If it's just separation anxiety I'm fine with being there for him.

If you went through this, how long did it last? Ideally I'd like his sleep a little more sorted out before the new baby arrives next month but if it's not I guess we'll just deal with it as we go!
