For some reason, it's really hard to find my daughter's size where we live and even on the Internet.  This may be due to the fact that a size 3 in kids is the equivalent of a women's size 5, which has largely disappeared, and I suspect that there is competition between women and kids for this size!  Thus, we were quite happy to find some rain boots in her size and at a reasonable price that are just girly enough without embarrassing me when I borrow them from her!
