Hi, how old is she? We have had a lot of issues with ds fussy eating but i think hes older than your dd (hes 4)
What worked for us was asking him beforehand, so he had a lot of controll over what he ate. Eg for lunch when we dont all eat the same thing i would ask him what he fancied. If he said meat sandwich i would show him the meat, let him taste it, then let him help me make it. If i were to just put a plate of food in front of him without his input i know he would just reject it.
For dinnertimes we all eat together and generally eat the same thing (unless its spicy or something i know he genuinely doesnt like) for eg spag bol. I will let him help me chop the ingreadients. When plating up i will call him in and ask him how mich pasta i should put in his plate, where on his playe he wants it where he wants the bol putting ect. I find that because he has chosen himself it really helps.
Not sure if this will help due to age, but its really helped in our house. Its really tough, we were getting 'im starving' but then no eating the meal, And then im starving straight after it. Nightmare i know, hugs.
Someone said to me, that its not that they don't like it, its more that they just dont fancey it at that moment and its so true!
