What exactly WILL he eat? You said no meat, does that mean he's vegetarian? Because every TS restaurant will have a vegetarian option....the buffets will have a fruit bar and salad bar selection. Counter Service are a little more difficult, but you can review the menus at allearsnet.com/menu/menus.htm to see which have something he'll eat.
If it's more "picky" than that, give us some examples of what he normally eats and we may be able to guide you to the places that serve the food he'll eat. One of the great things about Disney, too, is that they seem to be willing, within reason, to accomodate different eating requirements....no guarantees of course, but it's a possiblity. I know that some people will flame the idea of a "picky" eater having an eating requirement....I have learned that it can actually be a requirement. I have friends with a preteen that would rather grow weak from hunger than eat other than what she wants (the parents tried to "starve" her into submission but that backfired with almost 2 days of not eating), so while I don't personally have this issue (my kids will eat dern near anything, lol) I have great symphathy now. When we first met my friend and her daughter I thought she was just an indulging mom who didn't put her foot down and tell her daughter to eat what was fixed for dinner and not go about making a completely separate menu for the daughter only......boy did I learn better! My kids went through the "I don't want that" phase and I simply refused to make a separate meal for them, you eat what's served or make yourself a PBJ sandwich basically. But with this friend it goes well beyond that....the times they have tried to force her to eat she would get sick, violently so....and refusing to fix her special foods she'd simply not eat and she's already so thin and frail from the little she'll eat, that was pretty bad. She's been to doctors and eating disorder specialist but not diagnosised as eating disorder for some reason. Pretty sad to watch all they go through trying to feed their child.
Anyway...sorry to get off track....but tell us some of the typical things he eats at home, and we can try to find similar in WDW.
and some fruits and veggies. No meat, no fish.
He's 9 - I too, tried like your friends to sort of force him to eat. Made no special meals for him for a few days and hoped he would give in and eat what we were eating. The kid lost 4 pounds in 3 days - and he only weighed about 65 pounds to start with so that was not good. So I'm back to catering to his food pickiness - it's hard to justify to others when they say "oh he'll eat eventually" - really - we've tried - he won't!
The suggestions I've received here on places to eat are great - and since he does eat pasta that is an easy thing to get at many places!
Thanks everyone for the ideas.
