I love seeing I am not alone on the picky eaters!!!! I have several picky eaters and I serve Sneaky Chef foods I love watching them gobble down the mac and cheese that is full of carrots and sweet potatoes!!!
I don't make second meals and snack is usually unlimited fruit (to a point) and one granola bar per day or some other baked goodie (that has extra goodness in it!)
I have had children not each lunch for a couple of days and one little guy that never eats lunch or really any snacks. (Very stubborn and thankfully his parents don't get upset about it!) Funny enough not one of these guys have died of starvation!
