I used to keep on serving and serving at snack time until they were full.
I used to as well but then I had several children with massive appetites and honestly, 6 day care children were eating more food then my 2 teens and I had for supper. It was insane.it

Not any more. I have portion control, there is usually a bit of left overs if someone wants seconds but that's more there in case someone's lunch gets knocked over before being eaten.

I have one little boy here at the moment who is 22 months old, and if I gave him 5 bowls of lunch he'd still want more. His mother's view is that he will stop when he's had enough! But I'm sorry, I am not going to feed that child until he stops because his entire fees would go on food.

I feed appropriate portions, he's not starving, he's not upset with hunger and if she wants to feed him huge meals at home, then that's entirely up to her.
