# Anti\-colic bottle nipples and how to choose flow rate Which anti\-colic bottle nipples are available, and how should I choose the flow rate?

The three flows can be told apart by the hole at the teat tip: one small hole for slow flow, three small holes for medium flow and a criss\-cross X shape for fast/variable flow\. Haakaa Generation 3 Silicone Bottle Anti\-Colic Nipple \(S/M/L\) \- 2pcs: A flow rate too slow for the baby can build pressure behind the anti\-colic vent and push milk out of the bottle neck, causing leaks; moving to the next flow level can fix it\.

(listing) Every value in the table is a fact RoboTrunk checked, linked to the page it came from\. A dash means no checked fact fills that cell\. Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live\. Written 2026-10-14T06:04:12.801Z. This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page. RoboTrunk never takes the payment or sees a card.
