I'm begining to think that I need to limit the food I serve to my day home kids!

I'm a firm believer that kids will eat until they are full and can listen to their bodies in that regard, but I'm starting to wonder if being in a group setting is hindering that ability in the kids. At snack time some children are eating 3rds and 4ths, my food bills are getting ridiculous and more importantly I don't feel they are eating out of hunger; I think they're eating because the next one is still eating, so they don't want to miss out on something, or in one child's case, I feel their eating more to try to keep it from the other kids.

I don't serve junk, I follow the Canadian food guide, snacks and meals always have fruits and/or veggies, but I really don't see how a 4 year old needs to be eating 2 big bananas plus other items at snack time. Really, it's not all my kids, just a couple, but the rules have to be consistent for all the kids.

What do you do with your kids? I serve two meals and two snacks daily, not everyone is here for breakfast.
