They will fit most bottles with standard or classic size bottle openings, including our Nursette bottles, Enfamil Plastic Bottles, Enfamil GRAD-U-FEED Nursers, Mead Johnson Cleft Lip/Palate Nursers, and Snappies.
Typically used by older babies or those babies on a thickened formula. The cross-cut creates a wider opening allowing formula to flow through faster than our standard nipple.
When we were in the hospital with our daughter, they gave us these Enfamil bottles with disposable nipples to feed her with. What a life saver! These bottles are already premixed the amounts of formula and water in them. All you have to do is shake the bottle to mix the formula together! The nipples are disposable so once you use it once you can toss it out. The nipples are individually wrapped and come in different flow rates, depending on how old the baby is and how fast they drink the formula. These bottles are a little bit more costly than the other forms of formula but I certainly recommend that new parents keep a case of these on hand for emergancy situations or those late night feedings when you don't have the energy to prepare the actual bottle for the baby. These bottles are stored at room tempature and there is no heating required in order to feed them to your baby. It is the same formula that you buy in the powder, concentrate or pre made jugs, just in a more convient form of giving it to baby.
