And get her to a good reptile vet as soon as possible
She doesn't need crickets every night. if you feed the diet which I have linked. 3 times a week and dusted crickets, twice a week, she may well live a happy life.
Baby Food is an age old way of feeding crested geckos before Allen repashy made his commercial diet.
But please get her to a vet asap to see if it is a more serious problem,
