My oldest is 15, 14, 10, 8, 6, 3 my 3 year old is not a typical 3 year old. He is very, very mild mannered. Usually when people comment on how well behaved he is I tell them I paid my dues with the 5 before. We also have a fairly large house and have designated puppy areas. I don't plan to leave her unattended with a 3 year old anyway
