Acrobatics

Thien Nhan's "good" leg is now incredibly strong, reports the tot's mom, Mai Anh. "He can cover a lot of distance by hopping," she says. "He is very strong and hops around the whole house. He especially loves to jump and do somersaults."

A favorite trick involves jumping off a high desk, landing on "all-threes" and rolling across the room -- a move that scares poor Mai Anh half to death. "I told him that if he didn't stop horsing around like that he'd end up hurting his other leg too," she says. "The next time he did it I said, 'Nhan, what could happen if you're too naughty?'" and he said: 'My other leg could fall off too!'"
