In case you've forgotten, Jack is seven and Trey is almost 6. Yes, I know. Lots of kids have been riding bikes for years at these ages. Hmm. There are definitely great reasons why they've not learned to ride a bike before now, but it's still a bit embarrassing, I'll admit. Our driveway is crazy steep. No way any bike riding is happening there, although it makes for some great snow sledding with adult supervision. You can ride circles in the garage, but seriously, who is ever going to learn that way? Our subdivision has no sidewalks, and our house is right on the curve where it's difficult to see traffic coming. Does it count that I'm always holding a small child?
