He is about a month and a half old and i just realized that when i pet him on the head he shakes. Is this normal or what? I have another baby and they are brothers and he doesn't do the same. He is not cold or anything. Is he scared or something? He just kind of lays there and shakes when i pet him. Nothing else. Doesn't run or pull away. I always freak out on the little things but i just want to know if he is ok. I was laying in bed and i had him on my chest and i was petting him and he was shaking like crazy ): I felt so bad!
