My husband looked it up and said it's pretty common on the spectrum, but my son will say something and then repeat it in a whisper to himself. He hasn't noticed that he's doing it unless we comment on it. My husband said we need to correct him when he repeats himself like that.
I told him I think I did it for awhile too when I was little and he said "maybe you had autism too"
It's been more prevelant the last week or two, not sure if this is something long-lasting or not.... anybody else have experience with it?
