Sam the Gymnast.

Sam is following in his mother's footsteps as a little gymnast. He and Tyler Hansen go to gymnastics together to learn how to jump on, swing from, and tumble over things. Pretty much all the same stuff Sam does at home all day anyway. At least none of our stuff gets broken this way. Here's a link to a video:

Sam swinging from a bar kicking a ball. Tricia freaked out when I let go of Sam and let him swing by himself.
