My son is doing the same thing. Unfortunately, it's my mom that offers the "buffet" while I insist on just offering a few choices. Trust me, it will get worse if you keep offering him too many choices. I give two - this one or this one? I'll say, while offering, say, soup or cheese and crackers for dinner. I have long given up on teh Martha Stewart-esque ideal of giving my child nothing but the healthiest stuff all the time. While I am still reading labels and eating green, I don't make a big deal if my son chooses to skip 1, 2, or even all 3 of his meals, preferring to only snack. I find that when I don't fuss about it, the tantrums and fussiness subside. As for the "big boy chair," my son also has longed abandoned his high chair (although, every once in a while, he wants to sit in it and cuddle with his blankie). I let him sit wherever he wants, but again, I only give him the choice of sitting at the island or on the table -- NOT in front of the TV or elsewhere, where I have to follow him around with a spoon. If he wanders, I let him and I don't chase him - I figure if he is hungry enough, he will stay in place to eat.
