The current study used a liquid fading procedure to establish milk consumption in a child with autism spectrum disorder. Before the study started the participant was still drinking powdered infant formula and had refused to switch to whole milk. All procedures, including data collection, were implemented by his mother through consultation in a home setting. The liquid fading protocol consisted of 8 steps, in accordance to the procedures used by Luiselli, Ricciardi, and Gilligan (2005) with modification. Baseline and intervention phases were evaluated by using a changing criterion design. At the end of the intervention the participant had reached 100% whole milk consumption within 3 months; this result was maintained 1 and 3 months later. The social acceptability of the intervention, as indicated by the mother, was high. This study suggests the effectiveness of antecedent-based intervention, without escape extinction, by the parent in a home setting; the procedure was able to be implemented through consultation.
