Who is this kid??

There is this kid living in our house. I don't really know who he is. He looks like Ethan, but he doesn't act like him. Ethan is shy and clingy. He doesn't like new people, or even friends, just mom and dad. In fact, he likes mom and dad so much that he won't even play by himself. He has to be involved in whatever we're doing, even if it means sitting on the couch folding laundry.

Not this new kid. He will spend hours running around the house, climbing, and jumping from ever increasing heights, regardless of what we're doing. He enjoys playing with other kids and doesn't shrink away from strangers. He even runs away while out shopping, off to explore new things and hide from mom.

We don't know who this little independent kid is, but we sure like him!
