One night I heard lots of giggling as Erik was putting Kellan to bed. I figured Erik was playing another game of "tickle torture" and it would be a bit of a fight putting the little guy to sleep when they're having that much fun.

Later I asked Erik what they were up to.  He said he made planet Earth out of play dough (I have an easy-to-make recipe) and showed Kellan how it's night in one part of the world and day in another using the play dough ball and his nightlight as the sun. Kellan fell asleep clutching the ball.He is asking so many questions about how things work and why. It's not always easy answering these questions in a way that's satisfactory for a preschooler. If you don't give a good answer, they will call you out for your laziness - trust me on this one. And if the answer is too complicated, it doesn't really help encourage more questions.

I'm so glad I live with someone who can think of fun ways to explain something. I'm not always that creative or quick thinking, but it's always a fun challenge to think of ways to make even the most complicated concepts understandable for my kid.
