None of the above choices .He may become weaker as he gets older .He may stay in bed to gather his strength to walk more .He may develop muscular dystrophy later in life .
What may happen after moving himself a lot ?
He uses his legs a lot to move himself . I predict that , although he will have a calmer demeanour than his big brother , that he will be just as physically active . Confession time : This morning Finn and I went to the Grove which is a forest preserve / park that he loves . Anyhow , there a couple there with their son who is about the same age as Finn .
