Yes, DD6 is always talking, asking questions, singing, humming, or making what sound like nonsense noises of some type or another. She is also a singer and has been performing (by her choice) since age 3, although I think this choice is a result of the behavior rather than a cause. She has excellent pitch, fortunately, but I am an introvert, so I am often challenged to expand my patience.

She does, however, also exhibit attention challenges very similar to those described by chris1234, so I often wonder how much of the behavior is possibly related to undiagnosed ADHD vs OEs.
