Is it normal for a 7 year old to walk on top of a living room table with their shoes on or get on his knees in a restaurant in a booth and look and play around at the people sitting behind us or climb under the table in a restaurant or to jump up in down in a infant car seat and not know what a penny is or how to tie his shoe? My husband son does these things and I didn't know if it was normal for a child that age to be doing.I don't have kids
