The tallest building in the world, the smallest video camera used by the C.I.A., the most baskets ever shot in a single game. Boys want to prove themselves, to be masters of a universe. Collecting information is a way of getting their arms all the way around a topic. If that information involves superlatives — the biggest, strongest, fastest — even better.

A good tactic is to act a bit ignorant, seeking their expert knowledge no matter how meager. Being enthusiastic and captivated is a deposit in the bank of good will you establish with your son. This esoteric, passionately communicated information is their gift to you; by asking for details and appreciating the answers, you show your gratitude.

Help him change the channel

If he’s reciting the same roster of dinosaurs you’ve already heard 50 times, consider that he’s run out of material. Little boys need more information not only to sate their curiosity but also to keep you captivated.

The surest way to refresh the monologue is to feed him some new facts and experiences via books, videos or outings: a trip to the library, harbor, train station or farmer’s market; or a big-ticket excursion to the museum, aquarium or zoo.

Shoot hoops

Let him talk in the dark, in the car, while moving, while waiting for the bus or sitting on the subway. In general he’s more comfortable chatting side by side than face to face. Holding an object in his hands eases tension, too. Your role is to be attentive and receptive to the commentary. Once boys can write, some prefer to communicate a big thought, confession or heartfelt sentiment on a piece of paper and slip it under your door rather than to say it in person. If you leave little notes every so often on his desk, night table or pillow, you’ve opened up an avenue of communication he hadn’t realized was available and he’ll be more likely to do the same.

To get your message through, avoid “constructive criticism” containing abstract words such as inappropriate, focus, disruptive and success. Especially when you use them with a stern tone, they sound to your son like the wah-wah-wah of the adults in “Peanuts” cartoons. Instead speak loudly, calmly, simply. Repeat. Hinting may be lost on your son. Long, earnest downloads about anything — from areas in need of improvement to detailed plans he’s excited about — are unlikely to stick. So think of your conversations as shooting hoops. You say a little something, then another little something, and sometimes it goes through and you get a basket.

Cherish him

Ian McEwan, in his novel “The Children Act,” describes how the 8-year-old’s release of “a silvery stream of anecdote, reflection, fantasy” created in the adult listener a “wave of love for the child that constricted her throat and pricked her eyes.”

Shower your son with the easy affection, appreciation and tolerance you show your dog.

He can lead you on an incredible journey if he trusts you, if you make the time, and if you are willing to follow.
