I know this is an odd thread. However, my daughter (who's 7) has ASD, she is nonverbal. She sees a specialist speech therapist, they told us that children who are nonverbal, and who have ASD, come on leaps and bounds if there's an animal involved. Usually a rabbit is best.
I have considered it, but I'm not sure a rabbit is right for us. I don't think it would be fair on the animal - I wouldn't treat it bad, I'd feed it, give it a nice home, etc. but I don't particularly want one! Would you get one, if you knew it would help your child?
