Colt is learning to sit up and doing very well. He gets excited playing with his toys and then looses his balance! It is so fun to watch him. He has also found his feet and now tries to eat them and everything else that he can get to his mouth. He will be 6 months next week and will begin baby food. I am sure that he will love it. At his last appointment he weighed 19.4 lbs so we are shopping for a new car seat. I will post all of his stats next week!
