I am so proud of you. Your determination and steadfastness have enabled you to accomplish so much! What some people call stubbornness, I call stick-with-it-ness, and the ability to stand up for what's important to you. It's sure to continue to serve you well, son, and I'm so glad you know your own mind and are strong enough to express it.
A letter to my almost-thirteen-month-old son:
You may think you can outlast your mother in persisting in waking up just as she lowers you into your crib all night. She's here to tell you that you get your stubbornness from her, and she's perfected it. YOU CANNOT WIN. Also, if you don't stop repeatedly throwing your toys onto mommy's MacBook keyboard (despite her constant attempts to thwart you), you won't live to see two.
Persistence may be an admirable character trait, son, but not when it endangers mommy's technological best friend.
You've been warned.
