My dd was only 6lb 7, and even newborn was too big, she was in early baby and tiny baby for a few weeks then fitted in newborn for about 3 months. So I do think its worth me getting newborn sizes and not skipping.
Just sorted all the newborn clothes I've got and they are mostly 0-1 months. H&M, Polarn o Pyret and a couple of packs of sleepsuits from Tesco are all 0-1 not newborn. This is the smallest size some do, so thought it was equivalent of newborn but now I'm wondering if I need newborn too? Is there much difference?
This size didn't really exist with dd in most places, not tesco anyway, so I'm not sure.
