I'm not a morning person, but that doesn't mean I waste the small hours sitting, all bleary and grumpy, until the caffeine kicks in. I don't know many parents with that kind of luxury. No, most mornings I've engaged in some form of exercise, cleaned something, cuddled somebody, planned a meal, and at least glanced at my news and social media feeds.

One morning this week, that last item on my pre-dayjob ToDo List woke me up faster than a cup of strong [insert psychoactive beverage here]. I called my family together with a shout: "Ooh! ViHart posted a new math video!"

We learned and we were entertained. It was a great way to start the day: Growing smarter and happier together.
