John's 4 Month Check Up

John has grown well! He is 15.7 pounds and 27 inches. He got three immunizations, one by mouth and two shots. I thought he was able to roll over, but now I think one of the kids must have helped him as he has not rolled over since. We are a bit worried about him because he does not bear weight on his legs and doesn't pull up with his little arms. The doctor said that 90% of kids his age could. So, we are working with him and hopefully his muscles will get stronger.
