Olivia was 6lb 6oz and in 00000 for nearly a month. And like everyone else I was told to only buy 000 and roll the sleeves up! I bought a 000 pumpkin patch outfit (whiche have generous sizing anyway) to bring her home in and it was gigantic (it only just fits now!). A quick trip to the hospital gift shop (and $40 later #-o ) she had clothes.
