The Playtex Drop-Ins® Liner is a soft, disposable liner that fits 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.
