Giveaway- Cable Left, Cable Right: 94 Knitted Cables

I was at a recent blogger’s meetup—chatting, sipping lukewarm coffee, and exchanging parenting war stories—when the conversation turned to toys. More specifically, the boxes toys come in.

“You know,” I laughed, “my kid unwrapped a fancy, interactive toy last Christmas, and five minutes later, the box had become a spaceship… the toy? Completely abandoned.”

That’s when Dr. Lucy Harper, a warm and wise child psychologist with a mischievous grin, chimed in: “Oh, the box wins every time. And there’s a very good reason for that.”

Naturally, I had to ask her more. What followed was one of the most fascinating, reassuring conversations I’ve had as a parent.

Me: So, Lucy—why do kids love playing with the box more than the actual toy?

Dr. Harper: Honestly, it’s one of the most developmentally beautiful things kids can do. When a child chooses the box, they’re choosing imagination over instruction. A toy often has one purpose—it sings, it moves, it lights up. But a box? A box can be anything. Kids see endless potential in something we adults might just toss in the recycling.

Me: So you’re saying it’s not just them being weird or ungrateful?

Dr. Harper: [Laughs] Not at all. It’s actually a wonderful sign of creativity and cognitive flexibility. Think of it like this—boxes offer what we call “open-ended play.” There’s no one way to use a box. That freedom gives children the chance to invent, experiment, and take charge of their own playtime. It helps their brains build problem-solving skills, storytelling ability, spatial reasoning… the list goes on.

Me: Okay, but does it really help with development? Or are we just romanticizing cardboard?

Dr. Harper: Oh, it absolutely helps. When your child turns a box into a rocket or a cave, they’re engaging multiple areas of their brain. They’re building narratives (language skills), exploring size and shape (early math concepts), using fine and gross motor skills (tape, scissors, crawling inside), and even practicing emotional regulation. That “I made this myself” feeling is powerful for confidence.

Me: You mentioned emotional regulation—how does box play support that?

Dr. Harper: Great question. Sometimes, boxes become cozy hideaways—reading nooks, forts, quiet spots. For many kids, that’s self-soothing. It’s their way of saying, “I need a break from all the noise.” And giving them space to retreat into a world they’ve created can be incredibly comforting.

Me: I’ve definitely seen that. So how can parents support more of this kind of play?

Dr. Harper: Start saving boxes! Seriously. Don’t rush to recycle them. Offer markers, tape, scissors, scrap paper, fabric—just let kids take the lead. You’d be amazed what they come up with. And here’s the secret: you don’t need a Pinterest-perfect play setup. The messier and more imaginative, the better.

Dr. Harper’s Favorite “Box Play” Ideas
Before we wrapped up (pun intended), I asked Lucy for some of her go-to box play setups that parents can try at home. Here’s what she shared:

The Spaceship Command Center
“Flip a large box over, cut a few windows, and hand over some foil and paper plates for the ‘control panels.’ Bonus points if your child names the spaceship and creates a mission.”

The DIY Café or Bakery
“Boxes make great shop counters. Set one up with play food or paper treats, and let your child take orders and serve customers. This builds storytelling and social skills.”

Wearable Cardboard Costumes
“Kids love making robot bodies, animal masks, or even cardboard wings. It blends creative expression with physical movement.”

The Crawl Tunnel or Maze
“Especially fun for toddlers—just tape boxes together to make a crawling path. It feels like a mini adventure.”

The Giant Art Canvas
“Flatten a box and let them draw a city, a racetrack, a jungle… whatever they dream up. Then use toy figures or cars to play out scenes.”

Me: Last question—what would you say to the parent who feels bad that their expensive toy got ignored?

Dr. Harper: I’d say: it’s okay. Your child didn’t reject your gift—they just found a different way to explore joy. Playing with the box isn’t a failure of the toy—it’s a success of their imagination.

And sometimes, the best toy is the one that didn’t cost a thing.

So next time your child dives headfirst into a cardboard box, don’t worry—embrace it. You might just be watching their creativity take flight.
