I'm seeing some intentional humor creep into Jacob's actions and vocabulary. It's actually pretty funny because he'll do or say something that's totally off the wall, and then he giggles at himself and looks at us like, "Aren't I hilarious?"
The other night, I was changing him into his pajamas and singing, "You Are My Sunshine." After I finished, he gives me a little smile and very emphatically states, "I take your sunshine away, mama! I put water on it!"
Such a naughty little dude.
