The Playtex Drop-Ins® Liners are soft, disposable liners that fit inside the Nurser bottle.
As your baby drinks, the liner gently collapses, preventing air from mixing with the milk. This design mimics breastfeeding by ensuring a steady flow without the need for venting, which can help reduce colic and gas.
Once feeding is done, you can simply discard the liner, making clean-up quick and easy for busy parents.
