My DS was probably just coming out of 000 and going into 00, he is still in 00 but slowly going into 0's. He is currently 76cm tall. Every baby is different, I think sizes go alot on the babies shape rather than weight
Oh how I wish she was still in 000 - I have so many outfits that size that I just adored! LOL.

The biggest problem I have with her moving out of the 0's, is it seems to become near on impossible to find jumpsuits in size 1. Except bonds stuff, and for some reason I'm just not a fan of the wondersuits.
