Bottle Nipple Flow Rate Finder
What a Bottle Nipple's Label Doesn't Tell You
Search 26 common bottle nipples by brand and see how fast each one actually delivered milk in a published lab test. Nipples with the same label, like slow flow, delivered very different amounts.

How to Use This Data
The study's authors concluded that a nipple's name gives no clear information about its flow rate, and that both flow and consistency matter. Two nipples sold as slow flow can deliver milk at very different speeds.
The numbers help a conversation, not a purchase decision on their own. Bring the bottle and nipple your baby uses to a feeding evaluation, where the therapist watches the feed itself.
What a Bottle Feeding Evaluation Looks At
Bottle-fed babies receive the same comprehensive evaluation at Integrative Wellness & Therapeutics as breastfed babies, with added checks of nipple flow rate, bottle type, pacing, milk leakage, fatigue, and feeding efficiency.

Sources and How This Tool Works
Flow rates come from Pados and colleagues (2016), who tested 10 nipples of each of 26 types sold for use after hospital discharge. Each nipple sat on a bottle connected to a breast pump that applied suction at 180 mmHg, the bottle held at a 30-degree angle; the researchers weighed the formula expressed in one minute and converted it to milliliters. The table shows the mean flow and the range across the 10 nipples, plus the coefficient of variation (CV), a measure of how much nipples of the same type differed: lower means more consistent. A lab bench test is not a baby; real feeding depends on the baby's suck, the position, and the milk. Products and formulations may have changed since 2016.
