give it time and practice. she'll get it. both my kids did.
one way to also practice is just to use a plain deck of cards (at least its cheap and she doesn't have to worry about bending the cards).
at lot of it is just getting use to the actually "shuffling" of the cards and fitting them together. she'll also get use to the hand movements so that it becomes more muscle memory.... just like learning the game itself, give shuffling some time and maybe 100+ shuffles.
