Not Just for Preemies: Used w/ Platex Nurser

My 1 week old, at-term grand-baby was gulping every bottle with a slow flow nipple %26 was understandably having a horrible time with gas. I gave these a try, hoping it would slow her down enough to stop the gulping and the gas. IT WORKED!! No more gulping and minimal gas. Note: I used these with the wide-neck collared Platex Bottles with the drop-in Liners. Loved these with my babies 25 yrs ago and now my daughter is using them with my grand-baby.

Excellent value for the quantity

My 4 month old baby was getting frustrated with the size 1 nipples that came with the Dr. Brown bottles so it was time to size up! This pack is an excellent value/quantity. Other retailers only sold these in a 2-pack and the price would have been higher for the amount I needed.
