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.

An image projection/display system (referred to generally herein as a “display system”) is provided to assist a pupil in speech development. The display system displays an image of a face viewed from the rear, as though the pupil were viewing a mask from behind. This “mask image” is projected in front of the pupil, and the mask image is manipulated to display proper lip, mouth, and tongue movement for a particular verbalization. Since the pupil is viewing the face on the mask image from behind, there is no need for the pupil to translate the lip, mouth, and tongue movements by reversing the left and right side. A tongue movement to the right on the mask image corresponds to a tongue movement to the right by the pupil.
