In my observation kids with older siblings tend to develop faster. As in they walk at an earlier age. I guess they get fed up with watching the older kids running around and being left behind. Older kids also often act as deputy parents. So I don't think kids from large families surfer from attention deficit. I am a single dad and often struggle to keep my child attention right through the day.
