It's ... a ... GIRL!

She slipped into the world at 4.21pm Sydney time January 30, with a healthy weight of 3.65kg (about 8 pound).

Despite all the racket she arrived sleeping peacefully.
After being lifted out of a warm bath, she gave a short cry of alarm and then was happy again.

Mother and daughter are doing very well,
little Rock number one is excited.

She doesn't have a name yet, we're waiting to see her character - so far she seems calm and peaceful.
