Taking care of a younger sibling ( I think he is older) is hard...believe me, i know. But it would be a lot harder if that child had disabilities like Helen's. They would be harder to take care of, and also it would be harder to play with them. That might of been a challenge that James faced. One of the funnest things about having a little sibling is playing, and that would be a challenge to do because she could not see or hear.
