Shortly after he turned one, we had a decent snowfall. I think he'd experienced snow in the first few weeks of his life, but this was the first significant snow he was able to enjoy - and he did. He was just about walking by then, and loved being bundled up in his little bear suit, outside in the snow.
This second set was taken on a separate occasion, when I had walked into town with the push-chair, and a little boy who was clearly wrapped up snug and warm. Despite the unexpected snowfall, as I walked home, he didn't even stir from his sleep.
