My son used to regularly have 4, sometimes asking for more after that... he eats so much that i'm worried how to afford the food bill when he is a teenager

He has gone off weetbix a bit, now he likes poridge or muesli (homemade),occassionaly rice bubbles but they don't fill him up enough... DH says it's my fault for offering him a choice, he just makes weetbix and puts it in front of him and he eats them.

My DD eats 1.5 at the moment.
