Dr. Brown"s Pacifier with Handle - 0-6 months The Dr. Brown’s Orthodontic Pacifier design promotes proper oral development for babies. The ultra thin stem is actually 2 times thinner than other pacifiers for minimal impact on baby’s teeth and mouth, and the hollow silicone bulb promotes proper tongue placement and reduces jaw pressure. Dr. Brown’s Orthodontic Pacifiers come in packs of two with a protective “clean” case. There are four color schemes and they include: orange, red, white & yellow; green, blue & white; and blue & white (clinical colors). There are three stages of pacifiers available (all three come with handles). Stage one is for infants 0 to 6-months-old – it is the smallest size is ideal for new baby’s mouth.
