Ah, it's DS4.5 to a tee! The child is an extrovert in a family of introverts, and he JUST CAN'T STOP TALKING!
It makes me crazy some days. I recently asked for 30 seconds of silence so I could concentrate on a math problem, and he barely paused before he asked if it had been 30 seconds yet! Argh!
Personally, I think it probably has more to do with personality than GTness, though the excesses of GTness probably exacerbate the personality traits of an extrovert. In fact, really the only things that make me think DS4 is GT is his excessive sensitivity and his excessive verbal ability (limited to talking). Beyond those, he doesn't really present as GT. But in those areas, he is SOOOOO excessive!
The one thing that works for me with him sometimes is giving him my undivided attention for a few minutes. I mean, looking him in the eye, being fully engaged, and not even thinking about anything else. Then he knows he's been seen and heard, so when I give him a concrete task that he can do by himself for a few minutes without talking to me--like LEGOs, for example--he is more willing to do it.
But this doesn't always work, and it only works for a short time.
Otherwise, find a good sitter and get some time alone when you need it. It's the best I've managed!
