my daughter gets all the hand-me-downs from all the female cousins
in the family and we just moved and I swear she has like 4 dressers full of
clothes from sizes 18months (some of which still fit) to size 5T....but yeah, don't go by "size" persay. Some of the 18mos stuff my daughter has is bigger than some of her 2T stuff...and some of her newborn outfits she couldn't fit into until she was 3 months old, but some of her 3-6 month onesies fit right away..
