How old is your daughter? My son was the same , he was so good with eating and then at 15 months he became fussy and would no longer eat fruits/vegetables/meats/pasta....anyway fast forward to today and he is going to be 7 in June and he still won't eat any of those foods!...He loves carbs , so bread , pancakes , crackers , chicken tenders , fries (you get the idea) are all a hit , he has on occasion tried something new but gags so much that he almost vomits , when he first became picky I still put those things on his plate just incase but he never touched them , you could try this and hope that she get's over this little phase as quickly as it started , some kids do. What I wouldn't advise doing is trying to force feed , this will just make it worse. For how limited my sons diet is he is very healthy , his weight is fine for his age/height , he is rarely sick. So I am just holding out for the day that he asks to try something and does and actually thinks...hey this isn't actually that bad!!
Good luck
