My kids are also exquisitely sensitive to taste, texture, and temperature. Both refused to have pizza with tomato sauce for a number of years (DS6 still does sometimes), which meant cheese-only (no other toppings allowed, of course). DD10 has just started experimenting with mushrooms on her pizza, but this is a recent development.

Also, hot-chocolate is really luke-warm chocolate. LOL

DS has finally discovered he likes certain salad dressings, so hoping for more vegetable-eating around here. DD still will only eat veggies if she can slather them in peanut butter (which - ugh, but at least nutritious...)
