Understand how Keep it Kleen pacifiers work for newborns and older babies. Learn about sizing, hygiene, and when to switch.

Quick Answer

Keep it Kleen pacifiers do not come in separate newborn and older baby sizes. Their unique self-closing shield design works for all ages, focusing on hygiene rather than age-specific sizing.

Why No Separate Sizes?

Unlike many pacifier brands that offer newborn (0-6 months) and older baby (6+ months) sizes, Keep it Kleen pacifiers are designed with a one-size-fits-most approach. The key differentiator is the automatically closing shield that keeps the nipple clean when dropped, which is useful for babies of any age. The soft shield material is gentle on sensitive skin, and the increased opening angle provides comfort as your baby grows.

What to Consider Instead of Size

Because Keep it Kleen doesn't use age-based sizing, focus on other factors: your baby's acceptance of the pacifier shape, the shield's fit against their face, and the overall hygiene benefit. The pacifier is designed for on-the-go use in various settings like airplanes, cars, and parks, making it a versatile choice from newborn through toddlerhood.
