Hmmm not sure Mel - DD1 is 4 and in 8 or 9 size shoes. She had really small feet until last year when they suddenly went on a growth spurt! She was in size 6 at 3.5y so would have been in size 3-4 at your DD's age.

My DDD1 is a bit clumsy now as her feet have grown - before then we never had any fals, trips etc so i can't help with that theory.
