Anyway, recently he is also walking with the aid of the walker used by Yuen Yuen's daughter. In fact that is his favourite plaything now, almost like a coveted goldplated lawnmower to him. He can walk to and fro the house countless times without getting tired. The ones who are tired are us, bending over to follow him so that he won't knock himself over.
I can't wait for him to walk on his own.
