What a stinker!

Jonah has been a stinker lately! He use to sleep straight through the night, no peeps even most nights. Then he started making some peeps in the night, but nothing major where we had to go in his room or anything. Then there were a few nights when we had to go comfort him in the night but it wasn't too terrible. Now, he has been crying in the night, too many nights now, and we have to go in and when we lay him back down in his crib when he's practically back asleep, he starts crying immediately. We don't know what is going on...he never seems like anything is wrong, he just doesn't want to be away from us. I have done a lot of reading and read that around 6 months this can happen for many reasons. One thing we have noticed is that when we get him in the morning, many times he has his head at the opposite end of the crib from where he started and he's on his tummy instead of on his back. This could be waking him up, so hopefully if he continues to flip and turn, he will get use to it so he doesn't get so angry! We have been so tired lately, but I just have to be thankful that he hasn't been like this for the entire first 6 months of his life! Thank the Lord for that!:)
