None of the other kids have this backpack at school so it is easy to distinguish. I get comments on how cute it is all the time.  I know that out of preschool he will probably want one that is more big kid, but I will get a good three years of use out of this backpack.  It holds enough, it is not meant to carry a kid's books for sure, but it carries my son's water, art projects, show and tell toys etc.  All the stuff he might need at preschool.
