I made my son a pair of denim booties with a suede sole for some traction when he figures out that those legs of his can be used for walking. To decorate, I simply put a little froggy button sewn on super tight so he can't swallow.
I forgot to mention that they're kind of dirty because he's been wearing them. He and his brother have discovered that if you mix water with dirt you get this really fun substance called MUD!!!
