J.S.
I know where your coming from. My oldest is this way!!! Eat a turkey sandwich? There is NO WAY in heck!!!
The things he does like...Goober sandwiches (peanut butter & jelly mixed together in a jar & it's really CHEAP at Walmart) he'll also eat some Lunchables, applesauce, pudding snackpacks, carrots & ranch, pretzles, sliced apples & carmel sauce, fruit rollups & fruit snacks. I have a hard time finding him a "main course" so we usually go with a sandwich, or a piece of pizza.
Good Luck!!!
