A pacifier weaning apparatus is provided that includes a shell or shell assembly providing a housing, and a nipple configured to protrude from the housing. The nipple includes a first end adapted to be held by the housing, and an opposing, sucking end adapted for insertion into a user's mouth. The nipple also defines a first chamber and an expandable, second chamber that are both open at the first end and extend in a direction from the first end to the sucking end, and the first chamber being open and the second chamber being closed at the sucking end. And the pacifier weaning apparatus includes an airflow-control component configured to regulate either or both a break pressure at or above which airflow through the first chamber is permitted, or a rate of airflow through the first chamber.
