Evenflo Nipples?

kenna_4

I use the Evenflo glass bottles with the classic nipples. I just bought the 3-6 speed and DH washed all the bottles today and mixed the new medium speed nipples with the slow ones, is there anyway to tell them apart? I'm trying to look at the markings on them but I haven't figured it out.

 

Thanks!

I think they have "S" or "M" really small on the flat part.

We were using the plastic Evenflo purely comfi bottles for awhile and those are numbered 1, 2 or 3 on the base. Not sure if they are same with yours.

The evenflow ones we are using have a rounder bulb on the tip and their a bit thicker. We use glass bottles but I don't think it makes a difference. Also, pp is right they often have an "M" or a "med" on the lip somewhere.

we don't use the glass ones but mixed up the slow and medium nipples. i couldn't for the life of me find any markings but i tested every single one by using a bottle filled with water and comparing the rate at which the water dripped out. i knew i only had 4 medium flows mixed in and was able to seperate all of them from the slow flows so i'm pretty confident in this "system" even though it was very time consuming. good luck!
