@santistevanmommie really? I've started to buy size 2 since on the package says size 2 is for 3 month olds ... but now that you say that im starting to think im wasting money !!
Like poster said before it's probably too big for a newborn. On the nipple on one of the sides it should have a number. 1 is for newborn until 9 or 10 months. I babysit a 7 mo old and she still uses size one nipples
