Sara suggested we put food on tooth picks to try and get Brig to eat something new.
Worked like a charm with Mangos. He kept saying "mmmmmmmmmm!" and handing me the empty toothpicks for a refill.
Just beware how you use this powerful tool. The next item I tried was zucchini. He put it in his mouth, chewed it, and spit it out. He hasn't touched a toothpick since.
