Dr. Brown's Natural Flow Preemie Flow Wide-Neck Baby Bottle Silicone Nipple, Slowest Flow, 0m+, 100% Silicone Bottle Nipple, 6 Pack

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.

I like this wide neck nipples. The flow is really good and convenient for the babies. Easy to clean as well.

Great. Leak proof, good flow of milk without being overwhelming.

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.

I recently bought the extra Dr. Brown's wide neck nipples to go with our bottles, and they’ve been a fantastic addition! These nipples are made of high-quality, soft silicone that mimics the natural flow of breastfeeding, making feedings smooth and comfortable for my little one.They fit perfectly with the Dr. Brown’s wide neck bottles, and the different flow rates (slow, medium, and fast) give us great flexibility as my daughter grows. What I appreciate the most is how easy they are to clean, and they don’t stain or retain odors.

Switched from round nipples to these from 6 months. Glad I did cause my daughter sucked her thumb. Didn’t want her to get an overbite n this helped. These were just extras I got with her bottles

Dr. brown wide base nipples are the only types that my baby accepts. They are soft for the baby but although they do have a size recommendation for the baby depending on the age, just know that is all depending on the baby's preference. my baby prefers a larger flow rate which the level 4 provides and also reduces the leak that comes out through the sides almost to a minimal if any. the nipples seem very durable and do not tear or stretch Easly and keep their shape. overall, these nipples server as the perfect size and function for my baby and would 100% recommend.

Good quality, breast shape, size it is bigger than I expected but it works as described , wish my baby would like it.
