Would recommend!!

The Dr.Browns preemie flu bottle nipple is great for my baby. I use to use the level 1 flow which is for 0 months babies, however I would see that my baby would always have lots of milk dripping down the corner of her lips every feed so I switched to this nipples instead and they work so much better for her, she is 1 month and a 1 week old and the slower flow helped reduce the leaking of milk of each feeding!

works good for 6 months baby

this product helps my feeding much easier and I did see the effectiveness of that. this prevented the milk leaking out, gas to overflow and my baby feels comfortable much more after changing her bottle to this as that being said it does not cause colic and the milk is always ready on the nipple area which meets the claim as welll. highly suggesting this

Perfect for added oatmeal

My 3 month old was using premie Dr. Browns nipples for regular formula, great perfect flow for him. However, we were advised to start adding a little oatmeal to his bottle (severe reflux) so it made the formula consistency thick and would not come through. Tried the size 1, also did not work. I decided to skip to size 3 and they're PERFECT for the thick consistency of the oatmeal bottles.
