One of the biggest issues that I have with Asa and Priscilla, is that they are not consistent with their expectations and consequences for Abbie's behavior. Surely, with all the parent training they have been given from JSA and other Autism resources, and advice from Brandi (ABA) and Jill (SLP), they would know that if you let a behavior "slide by" even once (such as jumping in the pool with clothes on, swimming with no clothes on, or opening the garage door) you are actually reinforcing the behavior as acceptable. Individuals with autism are extremely quick to "jump on " a behavior and make it a part of their routine, and it can be extremely hard to break them from it.
I am an elementary school teacher with experience teaching very young children, including those with high functioning autism. It has been my experience that it can be very easy to let a behavior "slide," when you feel you can't stop and give your full attention to redirect or correct it, but by allowing the behavior (even once) to take place it can take forever to undue or replace it with a more favorable behavior. It can become a lesson in futility, and in the case of Abby, this is just what her parents have created over and over again. What makes it even more unfortunate, is that they knowingly let behaviors slide! I feel for her teachers and paras when she returns to JSA, and for Brandi if and when she returns for therapy sessions. They have their work cut out for them for sure.
