He is a little on the small size, but that's OK, he is a handsome boy and will be a beautiful boy full grow. As long as he is healthy that's all that matters. We have a sweet girl that started out a beautiful big boned girl and when she got about 10 months old decided she wasn't going to grow any more and stayed about 40 lbs or so. She is a healthy and happy little girl. Your boy will start to get tall and lanky the first year then the second year start to fill out and widen out, so don't get discouraged. He will be the perfect size to snuggle with.
