Is there anywhere to see what an "average" shoe size is per age? I'm just curious. My mother was with me the other day when I took my boys to get new shoes. My mother was blown away that they "are only two sizes apart in shoes!". My 7 year old (just turned 7) is a 1 1/2. My 4 1/2 year old is an 11 1/2. Is this weird? I don't really care, but her remark made me curious.
