[My Isela]

That size sounds about right....my almost 2 year old is wearing a size 5.5/6. She seems to be growing out of them so quickly these days.
Luckily, my 3 year old has REALLY small feet...she can still fit into Target size 4 and in some brands even smaller (she is also only 34.5 inches tall and 25 pounds). My 3 year old isn't understanding how she is now getting the "hand me downs" from her younger sister.
I love to go to the used clothing store for the girls shoes since I can get them really cheap and they are usually almost new ;-)
