For some reason, it is not indicated anywhere (or did not see it), but both nipples are number 2. Since I have no parenting experience, as I understand it, the larger the number, the more the liquid drips through it. Avent bottle bought in the Russian Federation along with a breast pump fit perfectly. Anti colic system - pure marketing. Colic can be. It may not be. And it's not about the bottle. Another question - the child may not take this pacifier (also a mystery why). As an analogue, chico bottles are good if your baby hasn't taken an avent. Or you didn’t like the avent / didn’t come in. Nipples in a plastic container, for moving somewhere or storage, they will come off until the thin tendrils-latches break off, I think this shipping container is not intended for long-term storage. And most importantly, number 2 (from 1 month) is not so easy to find in the Russian Federation and they cost around 500 rubles for 2 pieces. These took two pieces for 300 rubles. A trifle, but nice)
