Great product, needed to size up from #3
These are perfect for my little guy. I know it was time to size up when it seemed like the size three nipple was sucking in when he’d drink. The quality is fine, the are durable and last months with regular use. I’ve used these for both of my babies, so very functional. These are compatible with the dr. Browns wide mouth glass bottles that we use, and the plastics ones too. The way the 4 looks on the nipple makes it easy to tell which ones are what size. They are extremely clear, and I usually order new ones once they start to look foggy after washing.

Sippy Cup Conversion
We are converting our 2 year old over to sippy cups to help his teeth develop. Design is great as it still prevents leaks, and size matches bottle tops perfectly. Quality and functionality match every product from Dr. Browns.

Reliable and Baby-Approved
These nipples fit perfectly with Dr. Brown’s bottles and provide a smooth flow. They’re easy to clean and durable. My baby transitioned easily to this level without frustration.

The best flow for my baby!
I am a big fan of Dr. Browns. My son has been on bottles wince he was only 1 week old, after trouble breastfeeding. These wide neck nipples have been perfect for him and he has never had any issues with gas. I leveled him up to the 2 flow nipples when it was time, and he did well with them immediately. To clean them, I always take apart the bottles and rinse the nipples with soap and water before putting them into my bottle sanitizer. They have lasted and are very durable. I have never had an issue with leakage.

Worked great for a while
These worked great for my Phillips Avent bottles. I bought enough for all 8 of bottles, I thought I was set when it came to sippy cups. Then around 16-17 months old my daughter found out you could push the middle into the bottle and milk would go everywhere. The first time she discovered this was in her car seat. The milk was in every nook and cranny of my car, this took months to clean. I had to take her car seat apart twice to try to get rid of the rotten milk smell. I thought it was a fluke and that she’s didn’t mean to. Then I seen her pop the middle in on 2 other occasions. After that we stopped the use of these tops and switched to nuk transition sippy cups. So yea I don’t recommend using these for Phillips avent. But overall the quality is nice and you get two tops for $3 which is a great price! It’s on me for trying to use them for Phillips.

Great transition nipple
These are great for transitioning from bottle to sippy cup. They fit the normal wide mouth bottles . Unlike going right to a sippy cup there is no leakage at all and baby went right from size 3 nipple to this one.

My baby is not used to it initially, and the milk appears to overflow from his mouth. However, he adapted fast and drink much faster than level 1 teat size.

Despite what google says, these wide neck nipples do NOT fit Avent bottles.
