Munchkin Standard Nipples 2-pk.

I was asked to rate this nipple as a toy. As a nipple, I give it a solid 4/5 stars. All babies get comfortable with a certain type of nipple. My son loved this when we used it after switching to a bottle and would not take anything else. However, if you are wanting this for its ability to change flow rates, don't bother. I did not appreciate a difference with the different settings. Still, my son will not take anything else (and it seems as though we tried them all!).Buy Munchkin Standard Nipples 2-pk.!
