T.S.
I just measured my just turned 5 year old daughter who is 46" tall, maybe they will meet one day on the basketball court. I just wanted to add my two cents that I always used the approach by pediatrician Dr. Sears and my own drs recommendation to have children graze on fruits, vegetables, and protien throughout the day. We have been fortunate that our kids (son who is 2.5) love brocolli, asparagus, carrots, cucumbers etc and we make sure they get their apples, oranges, etc and then for protein cut up chicken, chicken tenders, fish sticks, hard boiled eggs, etc. They get their grains too with whole wheat toast for breakfast with a glass of milk.
My dr really stresses that they should not have juice just milk or water. They need to eat their fruit and not drink it. (When they have colds I give them juice.)
At the end of the night we usually have a scoop of ice cream.
So to sum it up it is all day grazing in our household and never 3 sit down meals. Different but dr. recommended. Kids are healthy, slim, and energetic.
Take care!
