I've been through exactly what you're worried about. My 2 year old is also very picky and doesn't eat hardly any meat. He was in a home daycare and we recently have moved him to a center. I'm not sure what your setting is, but let me assure you that he will be fine. In both daycares the providers told me that he eats like a little pig! The home daycare would tell me what she made for lunches & snacks and I couldn't believe he was eating those things because he wouldn't touch them at home. I had to "spy" for myself one day, and sure enough he was stuffing himself with things I couldn't get him to touch! The difference, all the other kids were eating with him and eating the same thing so it was "the thing to do." With the center he attends now, we have to bring his lunches and snacks so I know he's at least getting things he likes. And they are very attentive to all the kids. There is even one little girl who brings lunch A and lunch B. If she doesn't eat lunch A then the staff is supposed to try lunch B. I couldn't believe they would be so accommodating. The one thing I did do is keep a bottle of Pedia Sure in the fridge. I asked them to give it to him if they ran into a day where he didn't want to eat. They have only used it once and he eats most of his lunch that we send. Some days are better than others, but since he's eating with his friends he does much better there than at home.
Hope that helps put your mind at ease a little. I know exactly how you feel, and mine is in daycare 5 days a week unfortunately... The transition will likely be a little rough, but you're little one will get there! Good luck!
