Relentless

Jada's getting better at listening to us, so it's a bit of a
transition in our heads to remember that Aaron can't yet understand
what we're telling him. Which is kind of funny, because he'll crawl
to places he's not supposed to crawl to or touch things he's not
supposed to touch, and if we say, "No, Aaron," and move him away, he
will immediately go right back. Three, four, five times in a row - no
matter, he'll go right back. He already has a football player's
build, so I guess this relentlessness would make him a linebacker
pursuing the quarterback.
