The first overnight

So, last night we had our little man for his first overnight in our home. We were a little nervous especially after our meeting with the FP the other day. They said he was totally afraid of the dark and wakes up during the night screaming our caseworkers name. (keep in mind the FM is totally upset he is moving and won't even talk to the caseworker) She also said he is a mommy's boy and doesn't like being without her at night. Said he has horrible anger issues when he's tired. He had a blast with us. Went to sleep with all the lights off by himself and slept all night without a peep. When he woke up he came and found me and got lots of hugs and kisses. He never once mentioned the Foster family or their kids. But talked about our kids the whole drive to our house (2 1/2 hrs). When he had to leave this morning he cried. Wednesday is moving day and can't come fast enough.
