How long did baby last in newborn size diapers? I am looking at stocking up - how many newborn size should I buy?

Newborn diapers are used very fast and will also be outgrown very fast. It depends on the weight of the baby upon birth. I only used 2 packets of Newborn size from Huggies and I have to start using their S size. Baby was born 3.6kg As baby is breastfed, they will usually poo and you will need to use alot of diapers so do not need to stock up newborn ones. For me, i stocked up more of S, M & L.
