Oliver took his first 5 steps on his own over the weekend. Not once but twice, although the second time was a bit wobbly. And he can now climb up the bed and the sofa, so we have to constantly watch over him lest he falls over.
Come to think of it, we have been doing that ever since he has the walker.
He also said "bird" after us when he saw some mynahs at our office. So that's another milestone over the weekend.
