Part of being a parent to a 4-year-old is surrendering yourself to the routines and rituals that govern your child’s day. For my son, Max, that means always letting him be the one who gets to push the elevator button in the morning, and keeping the chicken nuggets from ever making contact with the mac and cheese on his dinner plate. And when he wants some recreational screen time, it means allowing him to see the only thing he’s wanted to watch for the past several months: “Yellow Submarine.”

I can’t quite remember how this 1968 animated musical movie inspired by the Beatles became Max’s go-to viewing material. I don’t know how it overtook TV offerings like “PAW Patrol” or “Thomas & Friends,” so unerringly calibrated for contemporary tots, in his imagination. But now, twice a day, he and I sit on our couch and watch hand-drawn versions of the Fab Four set off in their comically elaborate watercraft, sing their beloved songs and rescue Pepperland from the music-hating Blue Meanies.
