I'm going to tell my husband I don't want the kids eating my food
Why don't you want them eating your food?
I spent so much time preparing it and I am hungry.
It is understandable to be upset about being hungry and not have eaten but you should always make sure your children eat before you do. It could get your children taken away if people find out you are not feeding them.
Alright I'll grab some food right now.
Families are expected to eat together. Next time you can prepare extra so you have enough for leftovers and you can save time cooking for a few days.
