Sometimes if they don't eat all of their food I will finish it. It's not an all the time thing, though. Sometimes my 6 year old dd will share with me. I also don't let them just pawn their food off on me so they don't have to eat it.
depends. Last night we had pizza. my dd took a couple slices of my favorite (green pepper, onion, sausage) and peeled off the tops, only eating the crust. She left behind cheese squares with topping. I didnt want to waste the best part so instead of getting another couple slices I ate her toppings.
