Physical Therapy Evaluation - Beckham

Today I took Beckham to a physical therapy evaluation. He is 16 months old and still not walking. He doesn't even like to hold my hands and walk. He also has a hard time bending his knees. At the conclusion of the evaluation, they decided that his knees were a little stiff but other than that he is just lazy and will walk when he is ready. He has 0 desire to walk. He doesn't even care that his brother is walking. When Brigham was learning to walk, he would fall a lot. Every time he fell, Beckham would laugh at him. :-) They gave me some exercises to do with him and told me to come back in 4 weeks.
