Philips Avent Natural Response Nipples, Fast Flow (Flow 4), 4-Pack, SCY964/04

I got them for many reasons. First of all I got the glass one. I am one of these crazy people that avoid plastics and I know the lid is plastic and nipple is silicone but I feel safe and have piece of mind that nothing bad leaching to my baby’s milk during warming milk/formula. Second of all I love this nipple. It works and looks like real nipple/ breast due to its ripples. It doesn’t leak if filter or put up side down or fall. Great fit. The baby has to actually suck in order to release milk/formula. It forces baby to correctly latch which minimize the amount of air it will suck so this itself makes it great choice. Less gasses less upset tummy. Durable, wash them multiple times a day and sterilize by emerging in boiling water and it works really well.

Honestly this brand is my go to for bottles, I know different babies like different things. But mine has done the best with these, I also love how the flows are for different ranges. They are easier to clean with the brush and I’ve noticed that the quality is great. My only complaint is that the formula sometimes gets stuck at the top of I don’t pre shake it a little

Avent for the win! I went with these bottles again with my second baby because I love them so much, great quality. Easy to wash and they don't leak at all, even if it tips over on the bed. Once you find the right flow these are perfect for babies who suck bottles down too fast or choke on bottles. Since they only let milk out when baby sucks they don't drip to the back of baby's throat when they rest so no more choking!

We love these nipples. Unlike other bottle nipples out on the market, these only let liquid flow out upon the baby sucking/pulling it out (just like breastfeeding). You can turn these upside down without leaking. The numbers correspond to how MUCH liquid comes out upon the baby sucking. They hold up well over time, are soft, and withstand repeated washing. Highly recommend.

Perfect replacement ones! Never upgraded after these ones. Got the size 3 for my 6 month old and she is 16 months and still uses them.

Breastfeeding is important for me to maintain, so we bought these nipples to make sure that the flow rate wouldn't mess up my breastfeeding journey. They are easy to use and clean, and I recommend this brand to any mom who is looking for bottle options

my brother loves these so much and they don’t spill. they can be left upside down and won’t drop any milk but it also isn’t hard for him to get milk out!

I can’t get these anywhere in store they are always sold out of size 1. So I love that Amazon has them. My only problem is some of them started flowing faster like the hole got bigger or something, but that’s maybe because I had to use them for a couple months with my baby.
