These pacifiers are suitable for most newborns and can be used until a pacifier is no longer needed. We do suggest switching out pacifiers every few months as needed.

Cleaning:

Before using the pacifier for the first time, place in boiling water no more than 3 minutes. Since it has a vented nipple, liquid will penetrate into the pacifier. When the pacifier has cooled, the water can be pressed out of the nipple to ensure hygiene. Clean often by carefully pouring boiling water over pacifiers.
