The great news is my little one rode her big girl bike without training wheels all the way to school and back this morning for the first time without any trouble.
The not-so-great news is I didn't achieve the same. I rode along on Hubby's grown-up scooter. When I lifted one hand to gesture a driver to hold up, I survived a spectacular wipe-out in the school parking lot, ripping my favourite blouse, my elbow and greatly bruising my right leg and knee. I hopped up and shrugged it off for the kids, but I admit I'm rather stiff and sore now.
Lesson: both hands required for scooter balance. Demonstration provided free of charge.
