I do it in meetings, where I find it helps me keep from mentally checking out completely. Rather than daydreaming, I'm focusing on something in the here-and-now. That makes it easier stay alert through empty business-babble, endless complainers, talk of issues I have no involvement in, etc., and still notice when a topic of substance and usefulness to me shows up.
So in other words, your DD has found a good coping mechanism for boredom, and the only problem here is she takes it too far at times.
This exactly. Signed, fellow meeting-doodler.
