Preemie nipples
Exactly as described. Excellent price. My granddaughter was born almost 8 weeks premature. These are the only nipples that she can use. Very difficult to find. Especially at a good price. Quality is excellent.

Slow flow is what premium’s need. They can’t eat fast and they work wonderful.

Great for baby’s that can’t handle the faster flow
Great for my daughter starting out she wasn’t a preemie baby but the regular preemie nipples and the size 1 was too fast of a flow for her we started her with these and worked our way up to the size 1

These are the slowest nipples on the market I assume! Perfect!
My baby has bad reflux and one of the only things that helps reflux is a slow flow nipple. These nipples are perfect and help her to not chug her bottles! She spits up a smaller amount and overall seems happier. They also aren’t as expensive as other bottle nipples and you get more for less money, which is always a plus.They fit the Dr Brown bottles just like their other nipples, and seems rather durable. I’ll have to see how long they last though!

Great Nipples
These were perfect for my premiee baby. I ordered these to the NICU and they got there right in time. She drinks very well from these nipples. Softer and the flow is perfect for her! 10/10 recommend
