Have you asked her? I send my kids the same snack everyday...when they get tired of it...then I send something new.
My son takes a whole apple everyday...one in his lunch and one for his snack...he loves apples and will eat them off the core. This morning he told me he wanted popcorn...so I popped him some and put it in a bag and off he went...he may now be on a popcorn kick for months.
My daughter takes applesauce and a piece of fruit leather. The fruit leather is not "fruit snacks"...but only fruit in it no chemicals or HFCS. The applesauce is only apples as well...no extra sugar or fillers.
If you find a snack she will eat...keep sending it until she wants a change...but my kids both like knowing it is going to be the same everyday.
