Is there a real difference between the 2... beside on being like a natural breast nipple??

Read the reviews.

Honestly I used both and noticed 0 difference in the actual bottle. The nipples are just different. I personally used the natural nipples but had a mixture of the bottles.

@liz41395 I seen something where you cant mix the natural nipple with the classic bottle without a Blue Ring.. what's that.. or does it matter

I had bottles donated to me so I had all the pieces. I think the blue ring is for the anti colic one. I never used it I don’t think. I remember having it though. It’s been awhile since I used them I guess I forget

@liz41395 aw thanks
