Food Issues

When will these food issues go away? My poor little guys went through so much that now they have over eating issues.  Yesterday Felix's teacher told me that Felix had to buy a school lunch because we forget to send him to school with one.  I immediately knew that he had done it again-- eaten his whole lunch during his first recess. She said that Felix told her that we didn't make him a lunch.  I understand where this all stems from but what I have a hard time dealing with is when the boys tell others that we didn't make them a lunch or that we don't give them breakfast.  I get that they have a survival instinct to consume as much as they possibly can because they were never sure when they were getting there next meal but it still hurts when they say we don't give them food.  Dennis had been telling his teacher that we don't give him breakfast so she was giving him whatever snack she could find first thing every morning. She said, that he said, "they don't feed me breakfast." Ouch. It hurts me because I go out of my way to make them healthy and yummy food.  I don't just give my sons a bowl of cereal and send them on their way.  I get up early to make them pancakes and eggs, oatmeal, egg sandwiches, omelets and other well-rounded breakfasts.  Felix has gotten in trouble in school for stealing other kids' snacks and Dennis has puked because he shoved food down his throat so fast when nobody was watching him.  Don't get me wrong, they have both made lots of progress but occasionally they relapse (for lack of a better word) and it freaks me out again. Anyone dealing with this issues?
