We went through these level 4 nipples faster than I expected, but the flow is perfect for my 9-month-old who’s finally getting the hang of sipping without choking. The silicone stays soft even after multiple sterilizations, which is a relief since my last pack turned stiff within weeks.

The vent system really does its job—my baby stopped gulping air and the fussiness at feedings is way down. These level 4 nipples fit perfectly on the bottles we already had, and the flow is just right for her now that she's older.

These level 4 nipples actually keep up with my son’s flow now, and he’s not gulping air like he used to with the faster ones. The silicone feels sturdy and the vent system still does its job, so feedings are way less messy. Definitely worth grabbing a spare pack.
