Hi mama! Honestly, newborns grow so fast, one of my mum friends started with NB pero by week 3-4 ang baby niya needed size 1 na, so maybe mix mo na with a few packs of small size para hindi masayang ang stock mo if the baby outgrows quickly. Every baby is different din, pero safer na may variety ready especially pag lumaki agad ang baby, so you're not stuck with boxes of diapers na hindi na pwede gamitin!
