Brennan's Big Boy Room

We have moved Brennan downstairs to his big boy room. He is still sleeping in a crib but is not in the nursery anymore. We wanted to make this transition now so that he doesn't think it is the baby's fault that everything is changing. :) He is okay with his room but does not love it. He has slept down there 2 (full nights)of the last 4 nights. The first night he cried a little but then slept all night. The second night he would not stop crying, so we brought him upstairs and he went to sleep fine. The third night he fussed a little but slept great. And last night was a challenge. He cried (very briefly when he got in bed), then he "talked" for about 2 hours, then he called "Mommy," then he screamed until we got him. We brought him upstairs where he refused to sleep in the nursery as well. So we held him for about 30 minutes and then he finally went to sleep. I am unsure if last night dealt with his new room or just not being tired. He has taken all of his naps in his new room just fine, so hopefully tonight will go well again.
