Vented bottle nipples?

Question

Does anyone have a problem with the nipples that have lil vents in them ? they are almost like there lil bubbles on the side of the nipples that have tiny slits in them to allow the right amount of air into the bottle..... anyone ever experience them leaking at them vents? i just bought 6 packs of bottles and 6 packs of nipples and all them leak... how can i stop them from leaking? what was your trick?

Answer 1

well if you hold them were the vent is on top by baby's top lip than they should not leak. i use the nuk kind and they only leak is someone turns to bottle the wrong way
