Brady has been doing well learning to ride his bike. By our third time out, he could already ride unassisted if Bryan got him started. Our fourth outing was definitely more frustrating for him - he is having trouble getting the hang of starting on his own. I think it's probably only going to take another time or two for him to get that down, too.
I posted this clip on facebook. You can see Brady riding, with Drew doing his best to keep up! Mallory tries to keep up, too, but it's impossible for her to go as fast on a tricycle. I think Santa will be bringing her a "real" bike for Christmas :)
