My pre-first daughter needed a bigger backpack for the folder system the teacher used for communicating to parents.  Trying hard to find a backpack that she liked online before venturing out to the stores, we came across this online and with Amazon Prime, it was super easy.  It was a little larger than I would have liked for a pre-first child, but did accomodate the folder and had two separate compartments with fairly easy to access spaces.  My daughter LOVED the color, the sparkles, the light up heart, the light up sneaker hanging off the zipper.  The only downside to this backpack is the fact that it does not have a water bottle holder.  Otherwise - she and all the other little girls love this backpack.
