Agree with momof4, here. I think that, whether she "wants" to or not, she should be sitting at the table with others for meal and snack time. What does she do now, just wander around and come back for nibbles?
And truthfully, I have (somewhat) stopped worrying about "making" kids eat certain things. I make it, I serve it, YOU choose whether or not you eat it. You WILL stay at the table for a reasonable amount of time. I will put a little bit of everything on your plate, and with the littlest ones (under 2-ish) I will not make you eat all of one thing before you can have more of something else. That rule starts at toddler age.
Having said that, I always provide at least two things at meal/snack, so they do feel like there is some choice. And if I make something that is a consistent thumbs down from ALL the kids, I take it out of the rotation for a while. We can always try that food again in a few months, but in the meantime, why throw food away??
Keep in mind that it can take exposing a child to a certain food up to 10 times before they will eat it. Just keep giving it to her! One day, she is going to pick it up and eat it.
I used to have a little guy who hated the vaccuum. I would pick him up and he would "help" with it. He grew to love it! Admittedly, I didn't usually get the job done perfectly that way, but he stopped screaming and shaking when he saw the thing!
