Thanks ladies!
Rachel- I just found Kmart baby clothes wash out of shape quickly, pilling occurs(is that the word- little balls of cotton..) all over them (and she is only 3.5 months so doesn't move heaps) and they look worn even though they are new. DD is getting too big for 00 so I have gone through 0000, 000, and now 00 clothing in 3.5 months! I know it will slow down but crikey! I am starting to buy size 0 which will last longer on her, but just wanted others' advice!
