Help! I've got myself into a pickle. What, in H&M sizing, would you consider the 'newborn' size? Their sizing is <0-1m = 2.5 kg 0-1 m = 3 kg 1-2 m = 5 kg Compared to John Lewis: Tiny Baby = 3.1 kg Newborn = 4.1 kg 0-3 months = 5.7 kg I've got clothing from both companies and now I'm confused how many I have of each size 😂
