Abstract
In the current investigation, we identified two young children who consistently consumed liquids, but not baby food, after treatment with positive reinforcement for mouth clean (an indirect measure of swallowing) and physical guidance with re‐presentation of food. We examined the effects of an 11‐step stimulus fading procedure that involved gradually altering the concentration of liquid by adding baby food to the liquid. High levels of mouth clean were maintained in both children throughout fading, and increased mouth clean during probes of 100% baby food was obtained after conducting all 11 fading steps with one child and 6 of 11 fading steps with the second child. Negative vocalizations decreased during probes of 100% baby food after conducting the remaining fading steps with the second child. Gram intake of 100% baby food increased with both children after we completed all fading steps. Copyright © 2013 John Wiley & Sons, Ltd.
