(Newborn) Diapers Usage

Hi Mummies! From ur own experience, how long did your baby use newborn diapers before switching to S to M to ...? Or if you can remember how many packets of newborn diapers were used in total (Size of the baby if dun mind mentioning) I have some samples and also bought a few different brands. I'm not sure if I "overkilled" in stocking up the newborn diapers. #firsttimemom #pregnancy
