Why My Son Got a Potato Trick-or-Treating—and What It Taught Me About Rigid Thinking
The porch light flickered, and Milo’s ranger hat slipped over his eyes as a man dropped a large russet potato into his pillowcase. Milo stared down at it, then up at the man.
“That’s a potato,” he said, loud enough for the next group of kids to hear.
“It sure is,” the man said cheerfully. “Happy Halloween.”
Milo did not move. “But this is trick-or-treat.”
I could feel the familiar tightness in my chest. At six, Milo had a very clear idea of how Halloween was supposed to go: doorbell, bucket, candy. A potato did not fit anywhere in that plan. His little sister was already halfway down the walkway, her fairy wings catching on a bush.
“Buddy,” I said quietly, “just say thank you. We can talk about it outside.”
He turned to me, his voice rising. “But is it a trick? Do I have to eat it? Why would he give me a potato?”
The man smiled, but it was the uncertain smile of someone who has made a joke and watched it land badly. I thanked him, guided Milo down the steps, and hoped the rest of the street would offer normal candy.
It did not settle him. At the next house, he asked the woman giving out gummy bears whether she had any potatoes. At the house after that, he wanted to go back and return the potato. By the time we got home, he was still repeating the same question: “Why would he do that?”
His sister dumped her candy onto the floor and began sorting into piles. Milo upended his pillowcase, and the potato rolled across the hardwood like a small, dusty accusation. He would not put it near his candy. He also would not let me throw it away.
My first reaction was embarrassment. I worried he had seemed rude, or ungrateful, or like the child who cannot take a joke. Later, after both kids were in bed, I thought about how often this kind of thing happened: the meltdown over a substitute teacher, the twenty questions when the playground was closed, the way he repeated, “But that’s not the rule,” whenever something did not match what he expected.
This was not naughtiness. It was rigid thinking.
Children like Milo often understand the world in clear categories. Halloween means candy. School means morning meeting, then math, then snack. If the schedule changes, or a neighbor hands out a potato, the category breaks. Their brains may keep returning to the problem because the exception feels unsafe, confusing, or even unfair. Repeating the same answer—“It’s just a joke, relax”—rarely helps because it does not give them a new way to organize what happened.
The next afternoon, when Milo was calm, I got a piece of paper and drew two columns: Expected and Unexpected. We wrote candy, stickers, and pencils under Expected. Under Unexpected, he wrote potato in capital letters.
“Unexpected means different from what you thought would happen,” I said. “It doesn’t automatically mean bad.”
He looked at the paper. “The potato was unexpected.”
“Yes.”
“Can I throw it away?”
“Not yet,” I said. “First, let’s practice what you can say if someone gives you something you don’t want.”
We stood at our front door and did a role-play. I was the neighbor, and I offered him an onion, a toothbrush, and a rock. He could say, “No, thank you, I’m good,” or he could take it and hand it to me later. We practiced once in a normal voice and once in a quiet voice. He thought the onion was hilarious, which helped.
I also gave him only two choices about the potato: keep it on the windowsill for a week, or put it in the compost after dinner. More choices would have started another loop. He chose the windowsill.
This is the approach we have slowly built since then. When he gets stuck, I do not try to convince him that his feelings are too big for the situation. I name the concrete fact first: “You got a potato. That was unexpected.” Then I give him a small plan he can control. He does not have to like the thing, but he does have to use a polite voice.
At school, his first-grade teacher used a similar language. She wrote “Plan B” on the board whenever the schedule changed: “Because the assembly is this morning, math will be after lunch.” She did not wait for the confusion to start. She told the children the usual plan, the change, and when the usual plan would return. That small preview reduced a lot of repeated questions.
At home, we now use the same structure. If rainy weather cancels the park, I say, “The usual plan was park. Today is different because of rain. We will do puzzles inside. We can try the park again Saturday.” If he asks the same question several times, I say, “Are you asking because you need information, or because the change still feels weird?” Sometimes he says, “Weird.” Then I hand him a fidget toy or ask him to draw the new plan.
We also practice jokes and mistakes in ordinary moments. If I pour his milk into the wrong cup, I say, “Unexpected cup, same milk.” If his shirt is inside out, I say, “Different way, still works.” These tiny examples help him build flexibility without a big lecture. He still notices every difference, but he is slowly learning that not every difference is a problem.
The potato sat on the windowsill for six days. It got a little soft, and one eye began to sprout. I showed him the sprout and said, “It’s changing. Do you want to compost it, or should I?” He carried it to the bin himself, said, “Goodbye, weird potato,” and that was mostly the end of it.
He still talks about it, though. Before school parties, he asks what the treat will be and whether there will be a substitute. When Halloween comes up, he asks if the potato house will be open again. I do not know. We bought candy and stickers this year, and I wrote “No, thank you, I’m good” on a small card in his treat bag.
He may use the card. He may also stand on someone’s porch, stunned, holding another strange object and insisting that it is not supposed to be there. That part is still evolving. But the potato did not ruin Halloween. It just showed us exactly where Milo needed a clearer map.
