I don't know how many times a day I ask my children, "what do you have in your mouth?" If we are outside it is a leaf, dirt, a small rock, once a screw! (scared the s#$%@ out of me when I saw it!) Inside they find paper, dog hair, dog food, etc. Everything goes in their mouths... EXCEPT food!
Yes, my kids fight me on eating good food. B spits many things out or just blocks me from putting it in her mouth. Z just picks things up one at a time and drops the things he doesn't want onto the floor. Right now they won't eat their crackers, banana, pasta, grilled cheese, meat, and many other things. However, if I were to put a handful of dogfood on their tray, I GUARANTEE they would eat it!
