Philips pacifiers DentiStar pacifiers My child disliked them and only used them for a few seconds, 2 or 3 times. The blue ones are for newborns, and the green ones are for babies 3 months and older. Miffy pacifiers can also be used from newborn. Designed to be less likely to cause buck teeth. All items have been washed, sterilized, and stored at home. Thank you for your understanding.
