S.B.
I've been to two CIrque shows. The first one years ago was Quidam. It was very adult, darker and slower paced. I don't recall any children and I think it would not be enjoyed by kids. Last month I went to Frisco to see OVO. The entire time I kept thinking how much my five year old would have loved it (I think my two year old would have liked it too, but she's bit young to sit still for that long. :) ). It had a bug theme. Very cool performances, fast paced , fun costumes. The deeper parts of the theme of the show would have been over his head, he would have understood the general story. There were many children at that performance and they all seemed to enjoy it. So I suppose it really depends on which show you are considering.
