Hi all, Our 4year old son constantly nags me that he's hungry. Even just after a meal. Does anyone experience a similar habit with their child? He's 102 cm tall and weighs just under 15kg so I don't think he's overweight, and he does eat healthily (fruit or a sandwich, rarely biscutis or sweet stuff) but it's just the constant eating that seems to me unusual. I have been told that this age group "grazes" rather than eats three large meals a day, but this doesn't seem to me grazing, when he's just eaten a sandwich, he comes to me half an hour later saying he's hungry again!! Help or advice would be appreciated. Jess
