I bought Morgan her 1st pair of Robeez - Size 0-6 months. I had heard that they were such great shoes, but I just couldn't justify spending $25 bucks on shoes for an infant...hahaha!! However, once I got these I realized how awesome they are. Nathan would always kick his shoes off and so it was with his little sister too. Once we put these on she kept warm feet because she couldn't kick them off!! WOOHOO!! And of course they are so stinkin' cute with the little owls on them...hehehe!!
