There’s a scene in Grease where Leo, the head of the rival Scorpions gang, says to Travolta’s Danny Zuko before they drag race: “The rules are there ain’t no rules.”

It’s one of the many random lines that has stuck in my head from a lifetime of movie watching. I think about it a lot now in relation to parenthood.

Bun (as my wife calls him) is almost one year old and my main takeaway from that time is that there is no normal. How he eats, how he sleeps (or doesn’t), how he develops. How we teach him, what we teach him, how much screen time we give him.

There ain’t no rules. And Leo wasn’t slinging empty threats. He repeatedly rams Danny’s car and gashes his side doors with spiked hubcaps.

All Danny (and we) can do is hit the gas and hold on.
