My DD is 16 months and just started walking. We took her to get her first pair of shoes last week which were fitted and checked that the size was right by the shop. I know that kids her age grow extremely fast and I don't want to cramp her feet in shoes that are too small for too long so how do you tell when shoes don't fit anymore? At the moment I'm just going on the rule of thumb that my mother used which was to check that the toes aren't close to the end of the shoe.
