my daughter is big...she is two and she was always off the charts, from about three months on. She is chubby but not overly so, mainly she is just tall. Dad is 6 foot 4, and I am 5 foot 9, so I guess thats where she gets it. My son is also head and shoulders above every other kid in his class...he was a little smaller than my daughter at 2, and now he is just tall and so skinny he looks like I dont feed him!
