Finding a new reinforcer for your child with autism is like finding gold! Yesterday we discovered bubbles are the bee's knees. Alanna loves bubbles. So much so that when she sees the bubbles PEC on her PEC board (a PEC is a picture she can exchange for something she wants) she immediately brings it. We used this to get her to switch to a verbal request, and all day yesterday we heard "ba ba", "bubbles" and "gubbles". She will now request without the PEC; she'll even bring you the bubble vial and dip the bubble wand in for you! She knows she has to bring it to her mouth to blow but isn't quite sure how yet.
I love that she is talking and has converted a PEC into a very close verbal approximation in less than a day. But now our world is "gubbles, gubbles, gubbles!!" We have to hide them and distract her. Good thing children with autism don't have fixations... not.
