Izzie picked up on using the stairs when she was 14 weeks old. I bought her the stairs that go up to the sofa and she goes up them, but likes to fly down over them. I have a baby gate blocking the stairs going upstairs as they are open stairs and steep. She gets overly excited and doesn't watch what shes doing sometimes and I worry about her losing her footing and falling, or thinking she can fly over those also
(She is such a dare devil ) I am going to slowly start moving the baby gate up a step or two over the next couple weeks and see how she does.
