I did newborn and 0-3months. Baby barely fit newborn being 7lb 4oz and 21inchds long
I did up to 1 month & 0-3. Didn’t bother with the strictly newborn stuff and really didn’t need the 1 month stuff as didn’t last long at all😂 my son was 7Ib 8oz x
We did 3 sets of each size 0000/newborn, 000/0-3months. We also did a 00/3-6month set as we kept being told bub was going to be huge huge huge. Bub was 3.92kg, 54cm long. She fitted into 0000/newborn for the first 6 weeks of her life
