Well, Iona finally made it up the stairs today. She was playing out in the hall, so I thought I'd better check on her, only to find she was on the second step up. We'd got out of the habit of closing the downstairs stair gate, as she'd shown no interest in the stairs up to now, so I hurried over and followed close behind her. In no time she'd crawled up all 13 steps, and was very proud of herself. Now to teach her to come down just as safely!
