An anti-obstructive airway dental orthotic is described. The orthotic includes a maxillary retainer and a mandibular retainer releasably attaching to a plurality of teeth of a wearer. The retainers are attached by at least one strut, either variable in length or of a plurality of lengths, which exert a forward force on the lower jaw, tending to advance the mandible relative to the maxilla. This advancement of the lower jaw promotes a less obstructed airway in the wearer, while fenestrations in the retainers may allow for greater comfort and tongue movement.

The peristaltic teat is a cleanable teat which rewards the baby for making the same natural peristaltic tongue movement it makes at the mother's breast. The reward is that the baby gets (more) milk when making the correct movement. The consequence is that the baby will use the same drinking mechanism as at the breast. Hence bottle feeding will become closer to breast feeding which makes the combination of bottle feeding and breast feeding easier.
