hi, try not to get discouraged. Remind yourself she is still learning.
Each time you present a new food, how many times do you offer it to her? Babies can take a while to adjust to a new food. I put brocolli on Leobin's high chair 3 times before he even touched it. I put it on about twice a day, then by a couple of days he was tasting it, then a day or two later he was eating pretty much the whole thing. I only offer a new food on its own and give space between new foods. Keep in mind that this is all new, new smells, tastes, feelings with each new food.
I have found with Leobin, I need to give him one piece at a time, or he really doesn't eat well, you might find your DD likes to eat a certain way.
This the time for her to practise and play with food, while you can still fill her up with bm or formula.
