The Up-Lock Paciflo is a supervised, awake-time training pacifier designed to encourage healthy oral posture in babies and toddlers: lips closed, tongue up against the palate and breathing through the nose. Created by orthodontist Dr. Sandra Kahn, co-author of Jaws: The Story of a Hidden Epidemic. Not a regular pacifier The Paciflo works as a feedback tool for parents. Its design lets you see whether your baby is holding gentle suction inside the mouth, a sign that the tongue is resting in the right position. It is meant for short, supervised sessions while your baby is awake. Available sizes 0–6 months 6–18 months 18+ months Why oral posture matters How babies hold their lips and tongue at rest is part of how the mouth and face develop. The Paciflo gives parents a simple way to observe and encourage that posture from the first months. Important safety information Do not use during sleep. For awake, supervised use only.
