Two replacement nipples for the NUK Smooth Flow™ Pro Anti-Colic Baby Bottle. The one-piece integrated bottle nipple & collar makes bottle preparation and cleanup easy. And because the nipple and collar is only one piece, there are no leaks, guaranteed. This newborn bottle features a unique nipple design that allows baby to control the flow rate for colic-free feeding. Our Smooth Flow™ Pro nipple with a Y-cut design adjusts the flow based on how your baby drinks, adapting to their suction strength, ensuring they will always have the right flow rate.
BPA-free, dishwasher-safe bottle nipple; safe for sterilizer and bottle warmers, too

Great if you want to drown your babyThis bottle almost drowned my baby. 1 oz flew out in like 5 seconds. The nipple opening is huge! Leaks after first use. Would give zero stars if I could for the worst bottle.

Great for anti colic, not so great for leakingMy little one is 4 weeks old. We have used these bottles since day one. They are amazing for anti colic. But the biggest downfall is that they leak. A LOT! Perfect shaped nipple, great for breastfed babies, I have not found anything my LO does not get super fussy with besides these. I just wish they didn’t leak so much!

Good product .I like these bottles . It’s easy to read the measuring numbers on the outside of the bottle . They are easy to clean, and dishwasher safe as well. I also like the size of the bottle. It was really easy for my son to grab and hold it on his own. A lot also the flow wasn’t to fast, and it wasn’t to slow either. It was just right. My son seemed to have less gas while using these bottles.

Very, very leaky bottles! Do not purchase!!!For our first kid, we loved Nuk's original Smooth Flow Anti-Colic bottles. They did not leak. They were very durable. We bought a bunch and took them everywhere. Based on that experience, four years later, we recently purchased Nuk's Smooth Flow Pro Anti-Colic bottles for our second kid without hesitation, assuming they would deliver the same experience. These new bottles are a disaster! The redesign is horrible with way too many parts! Worse, they leak all over the place. They leak when vertical because the vent straw functions a bit like a pipette. They leak when stored horizontally in a stroller basket, picture included. All of this has happened despite Nuk's website claiming "No leaks, guaranteed." This is completely unacceptable! Nuk, you have permanently lost us as a customer. We are returning these bottles because they are clearly a defective design!

gas problemI bought the three pack of three. I have to take the bottle out and quizzed the nipple to allow air in the bottle. My baby still gets lots of gases and cries too much

NUK makes better nipples and bottles.I've had these for 4 months and have attempted to use them over the past 2, my son cannot "control the flow". The Y cut makes him drown in milk to the point he gets more all over New and him than inside him. I love NUK products and use the other NUK Smooth Flow bottles but these do not hit the mark for me.
