My DD is 4 and is the same height and size as the rest of the girls in her class. Yet when i buy her clothes i end up having to buy the 5-6 or sometimes bigger simply to ensure it will last her more than a month. This usually means you out of the little girls sizes so you end up having to pay more, or but clothes that look to grown up. Only company where sizing seems accurate the majority of the time is mini Boden. Do any of you find that children's clothes come up small?
