We rented a house for 3 weeks in the North Carolina mountains. I wasn't sure how Nathan was going to do walking around here since all the walking areas are up and down hills. But, 2 weeks in, Nathan has gotten quite a bit stronger by walking these roads. The attached video shows him walking up a big hill this morning. It's a bit hard to see just how steep the hill is, but it's pretty steep. We also have a small set of rock steps leading in and out of the house. He can actually walk down the steps. I'll try to get a video of that too. It's the very first steps he's been able to do, so it's really exciting.
