Second Childhood
There's a version of childhood you get to live twice, if you're lucky. Maybe the first one slipped past you. You were working to keep the lights on, keeping everyone fed, putting out the small fires that come with raising kids. That first year moves at a speed nobody warns you about. Were you awake enough to see how funny they were, how fearless, how determined to climb whatever was climbable? Or were you running on no sleep and a to-do list that never shrank?
Grandchildren can hand you the moments you were too tired to catch the first time around. You can slow down now. You can block off an afternoon that belongs to them and nobody else. When a problem starts to form, you have the patience to see it early, before it turns into something that needs fixing. And of course yours are the cleverest, the most inventive, the most charming of any children anywhere. (If you don't have grandchildren, nieces and nephews count too. So do grandchildren plus nieces and nephews, for that matter.)
Say "second childhood" and some people picture an adult sliding backward into something babyish and useless. That misreads what childhood actually is. Play is a child's full-time work, the way they poke at the world to figure out how it operates. You might not see the value in it while you're in the thick of parenting. They're forever getting into the cabinets. They want the same picture book read nine times running, and you don't have ten minutes to sit while they try to tell you something.
Take language, about as fundamental as skills get. A child builds it by using it, by talking and being talked back to. There's a narrow path to walk between answering baby talk in kind and asking them to say what they actually mean so you can follow. Babies and toddlers and preschoolers are running little experiments all day long. They copy what they see. How many of us ever sat down and studied early childhood education? The kids themselves will show you how to teach them, if you watch what lands and keep adjusting how you offer things.
You are not too old for this. You might turn out to be the best playmate a small person ever has, and it's never too late to relearn how to do it, even on the second pass. Time spent playing with a child is not the throwaway some people assume it to be. Raising children ranks among the hardest and most consequential jobs anyone does. So why hand it off to people who don't care, and why underpay and look down on the ones who do?
