I bought these for my 15 month old. I especially bought a size too big, hoping to get extra wear from them. Because of the styling, the fact that they are roomy is not a handicap, and she has been able to use them right away. They are great for indoors in place of slippers, or outdoors for playing in. They are much less slippy underfoot than her normal Clark's shoes, and because they are washable, great for in the garden. I can't recommend them enough, and just wish we had one in every colour.
