Sadie's tears when she does fall down are usually directly related to how sleepy she is. When she isn't tired or in desperate need of a nap she doesn't cry. She falls down, gets back up, and keeps racing around the room. I'd like to strap pillows onto her with bungie cords, because she could use some padding as she smashes around the house, or scarier still, outside.
I wonder when the sense of balance start to improve or if this is just a sign that she's going to take after her two clumsy parents.
