GS age 3 and a half, can have an almost adult conversation. I find it very disconcerting. He can watch a programme on TV and then repeat it almost word for word. His brother, 2 and a half talks complete gobbledygook, very loudly, all the time, but you know exactly what he means because of the intonation. I think he just lets big brother get on with it and I have no doubt that one day he will speak just as clearly - just biding his time!
The King is to resume some duties.
