Well, it looks like we've entered the "Why?" stage. It officially began this morning. That's not to say that Katie hasn't asked, "Why?" before today; she was just always content with whatever answer she was given.
But all of that ended this morning. This morning, on not just one occasion, but several, Katie wasn't content with the answer she got when she asked, "Why?" So, she kept on asking, "Why?" over and over and over again. Luckily, she's not into the that extremely annoying "Why?" stage where it goes on for hours yet. But she did get up to four times in a row.
And I thought this stage didn't come until around age three. This kid's not even two yet. Oy!
