Climbing down the stairs

Ria climbed down the stairs for the first time today. She has been climbing down a stair or two for quite some time now, but today she climbed down the full set of stairs. She was very careful and focused; with a serious look on her face she slowly slid down a stair a time on her stomach. Also, today is the first time she did a real outdoor walk. Holding our hands, she did a full round of the building campus, which is quite a lot of walking. She has been walking unaided around the house quite often for the past couple of days. Just a few steps at a time, after which falls and sits there smiling, then gets up and goes at it again. But she is loving it, and keeps walking around all she can.
