I breastfed my baby all through infancy and could not get her to take a bottle for daycare. My baby would only drink from these nipples. Still the only bottle nipple she'll drink from besides a cup or sippy cup. We loved these in the hospital I worked at and I loved it at home. Thank you for making my life easier Enfamil!

These are the only nipples that my daughter would use. We eventually moved up to the standard flow when she got older, but kept with the same "model". We used a combo of breast milk and formula and it worked great for both.
I just ordered them again for our second daughter (due any day now).

They're cheap too... so when they started to wear down or you left a few somewhere... you didn't feel crushed buying a second box.
But they washed up nice and worked great.

After we received the package, we did not open it immediately, as we did not need the nipples right away. When we did, recently, take one out to use, it had such a strong, toxic, chemical smell to it we immediately put it in a Ziploc bag and threw it away. There was absolutely no way we would have fed our baby with it.

Now we are not allowed to return the package and we cannot use the rest (11 out of 12 nipples) we have paid good money for. We are very dissatisfied and extremely disappointed.

They work great together with the 2 oz newborn bottles. I brought them to the hospital for use after birth in case supplementation was needed. I've also brought them out on outings to see the pediatrician. Very convenient. However, our lactation consultant said that these nipples still flow too fast and advised us to practice slow feeding techniques when using them, so that they don't interfere with breastfeeding. (i.e. Tip the bottle downwards sometimes so that baby is not gulping milk down with every suck, but rather working a little harder for milk. Baby might seem to suck in some air but s/he's not, so not to worry.)

Made it so much easier to have these for being out with the baby and wanting to make sure you had a clean nipple. We like the slow flow nipple, so it is easier for baby to go between bottle and breastfeeding.
