Stealing food

Wow...did you even bother taking the foster parent training courses? First of all, he's a teenage boy. He was probably hungry. How on earth was he supposed to know what you had planned for lunch? Second, considering the fact that this boy has had a rough life, he certainly may have some issues understanding that food will always be available to him -- although, after this post, I'm not certain that it is always available to him. A lot of fkids hoard food. It makes them feel safer knowing that they have food in case the adults in their life stop feeding them. If I were you, I would give him a shelf in the fridge or in the cupboard, and stock it full of foods he likes and let him know he is welcome to eat any of that stuff whenever he wants. Then again, considering how upset you are that he "stole" food, maybe foster parenting isn't for you.
