I am blessed with a picky eater as well. My daughter does not like meat (unless it is ground) and won't eat much vegies. It is so frustrating. We have had many a fight at the kitchen table. It is slowly getting better. I am very strict and yes I do force her to try the food or she must go to her room until she is ready to eat. I found what vegies she will eat (raw celery, peas or corn) and we eat those most of the time. Every once in awhile I do something new and she MUST try it.

When it comes to daycare I usually just make things I know the kids (and my daughter) will eat. If the food doesn't get eaten when I serve it then it comes out again for the next meal. My rule is what I cook is what I cook and if you don't eat then you do without (and get fed the same thing the next meal). Seems to be working.

I would maybe take some focus of trying new foods. Put the food in front of her. If she doesn't eat then take it away and serve it again next meal. No talking about it, nothing. She either eats what you serve or goes home hungry. It isn't as if you aren't offering her food. When she is hungry then she will eat.
