My ds is like this...Hes 20 months and eats twice as much as my oldest dcb. Hes always been a big eater, even as an infant...He is also extremely active, never stops running outside and playing inside...I don't think its right to limit a child if they are hungry...An adults emotional connection to food is not the same as a child....Obviously you do not use it as a reward or way to quiet a child, but at meal time if a dck asks for more, I happily oblige....Theres so many posts complaining about kids not eating at daycare, a healthy appetite is a good thing
