Jonah loves playing sports. We went to two birthday parties and he spent the entirety of both playing baseball, soccer and basketball! I was quite impressed by his boldness to walk onto a basketball court to pick up a ball and start "dribbling"... in the middle of a bunch of adults shooting hoops! Fortunately, the adults were extremely toddler-conscience and made a game of defending any little people who stepped onto the court. Or they stopped to help Jonah dribble or shoot. Jonah even got a few of them to throw the wiffle ball for him to bat - and made contact a few times!
Jonah doesn't stop at regulation - kid-sized versions of - sanctioned sports. Anything involving a ball and stick will do. He invents new games all the time at home with whatever he can find: a golf ball and stick, a paint stirrer and small plastic ball, a colander and basketball. If he can hit with it, he will!
