"I'd say it's not been his best Christmas ever. A lot of his time is spent sleeping which is essential for his recovery. He enjoys listening to music and having visitors in."
The mother said the past three weeks have been "heartbreaking" to watch her son go through the ordeal.
But knowing things could have been so much worse, she paid tribute to all the medical support, well-wishers and her son's friends for how they reacted to the accident.
One of the boys lay on the ground, cradling his mate's head on his shoulder, while also holding the impaled metal stake still.
"I don't think I could single out anyone, everyone involved from the time it happened to now has been amazing," she said. "But I'd say first of all his friends who did all the right things when it happened, the rescue services ... and everyone here at Starship who has been involved in his care."
The mother said the metal stake was being kept by the family for her son to decide what to do with.
"... it should make a good story for his 21st birthday."
