Do you have children? I once told my pediatrician that ds11 (when he was younger) wouldn't eat more than 6 items. She said "so what?" I've had kids who will eat ANYTHING, and kids who have very sensitive palates (initially - the older they get, the more they'll eat - they do have to try everything). I've learned the hard way not to force food (nothing like a little vomit at the table).
Sounds like my house. My DS eats everything, my DD could survive on spaghetti only. My husband suffers because of it, I just let it go. My pediatrician told me not to make eating and food an issue. He is of the belief that it is the worst thing you can do.
They are both growing, they are both healthy, that's what matters to me. If I have to make a separate meal for her every now and again, I do it. But then again, they both know, no dinner, no sweets or snacks. But I refuse to make food a point of contention.
