My baby will be 1 year old the end of this month and she is still in a size 2 they still fit pretty good. 2007priyanka every child is different so it would be better to go by measurements of the shoes and your Childs foot than to go by another child. I am telling you from previous experience. I used to go by other peoples child with their clothing and as a first time mom I always went by the size of clothing on the tag, but learnt real quick not to do that cause different brand clothing fits different so now I just go by measurements instead. Of course you can do whatever you want I'm just giving a little advice I'd hate for someone to go off someone else and get something and get it home and not fit like Jessica said it depends on the individual child. Just trying to help ;)
