Oh boy were we bad. The boy stuck to the sides like glue, except for when his friend's parents took pity and helped him round several times. I was able to move from the edge eventually. Only fell the once (but boy did it hurt. That ice is harder than I remembered! And as someone commented, I surely DO have more padding than I used to.)
So after the holidays I looked up lessons and we've been going Saturday mornings ever since, and often on Thursday nights too.
The best thing is that it is not only D and me but the other two have joined in as well. Atti especially. He flails about and constantly falls (you should see his knees - almost completely purple) but he perseveres. I have never seen him try so hard at something. It's a joy to see!
