What is this gesture a sign for?
My son is 3 and has an expressive speech delay. We are using multiple communications methods. He is starting to catch on to ASL (we're all hearing, so our experience is limited to baby sign classes and Bill Vicars). He has a number of gestures that he uses, which I'd like to help him turn into actual signs, as I would try and turn a babbled sound into a word by guessing at its meaning and then saying the word. For example, he LOVES the song "Wheels on The Bus" and asks for it by rotating his hands around each other or honking an imaginary horn (as done in the first two verses in this video https://www.youtube.com/watch?v=S9XZX3m06cE). Are these gestures similar to any ASL signs that I can use in other settings? I've tried searching lifeprint but can't find anything (besides that honking a horn is like YOUR/YOURS).
