The Sunday Night Stomachache
(and the 3-Step Sunday Sit-Down)

It’s Sunday. Around five o’clock, something shifts. Your child goes quiet, pushes supper around the bowl, and says the sentence you’ve started to dread: “My tummy hurts.”

By Monday morning the tummy is fine. By the following Sunday it hurts again.

If this started up in the last week or two, you’re right on schedule. The first days of school run on adrenaline and new-shoes excitement. Three weeks in, the newness has worn off and what’s left is the plain arithmetic of it: this is the thing now, and it happens again tomorrow. That realization tends to land on a Sunday.

Why worry picks the stomach

A five-year-old does not have the words “I am anticipating a difficult week.” What they have is a body. And a worried body does real, physical things — the gut tightens, appetite drops, everything feels slightly off. The ache is not invented and it’s not a performance. It’s worry arriving in the only language a young nervous system speaks fluently.

Which is why “you’re fine, nothing’s wrong” never works. Something is wrong — they can feel it. They just can’t tell you what.

The Sunday Sit-Down: Find it · Finish it · Park it

Ten minutes, early evening, before the bedtime rush. Same three steps every week, so it becomes a ritual instead of an interrogation.

1. Find it. Skip “what are you worried about?” — that’s a question they can’t answer yet. Ask the body question instead: “Where is it? Point to it.” Then get specific together. Is it a rock or a flutter? Hot or cold? Big as a grape or big as an orange? This sounds like a game, and it is one — but it’s also the naming step, and a feeling that gets described stops being a vague dread and becomes a thing with edges. Very often the words arrive on their own once the body has been mapped: “It’s an orange. It’s because of library day.”

2. Finish it. A worried child is watching the same short clip on a loop — walking in the door, not knowing where to sit — and the clip never reaches the end. So walk tomorrow all the way through out loud, in order, in ordinary detail: you’ll have cereal, we’ll do the blue backpack, Ms. Diaz opens the door, you hang your coat on your hook, then reading, then lunch, then the playground. Keep going past the hard part, because the hard part is not the last part. Every version ends the same way: and then I pick you up, and we come home. That ending is the whole point. The loop only frightens because it stops in the middle.

3. Park it. Don’t try to talk the worry away — give it somewhere to wait. A jar on the nightstand, a folded note under the lamp, a stuffed animal who holds it until morning. Say it plainly: “It can sit right here. It doesn’t have to come to bed with you.” Children take this literally, and that’s exactly why it works: sleep is what a worried body needs most and what worry is best at stealing.

Two things that make Sunday worse

Starting the conversation at lights-out. At 8:15 there’s no time to do anything with what comes up, so the worry gets aired and then abandoned in a dark room. Move the whole thing to five o’clock, when there are still hours of ordinary evening left to soften it.

Cancelling the week to fix the feeling. Skipping school on Monday buys one calm night and makes the next six Sundays harder, because it quietly confirms that the thing they fear was worth fearing. Take the stomachache seriously; keep the plan.

When to check further

Body-worry is common and usually passes as the routine sets in. But if the ache shows up on Saturdays too, wakes your child at night, comes with fever or weight loss, or a specific fear keeps surfacing — a particular child, a particular room, the bathroom, the bus — that’s worth a conversation with the teacher or your paediatrician. The Sunday Sit-Down works best on a general dread. A specific problem needs a specific fix.

Give it a month of Sundays

The ache rarely vanishes after one good conversation. What shifts first is the shape of the evening: less “I feel sick,” more “can we do the jar?” Once a child has a reliable place to put tomorrow, Sunday stops being the night everything piles up — and starts being the night it gets unpacked.

This week’s comic

A four-panel Mira & Lumo comic. One: Sunday supper, and Mira slumps over an untouched bowl with one hand pressed to her tummy while a small grey Whisper Worry sits on the table edge and Lumo, a little glowing golden friend, hovers close. Two: on her bedroom rug, Mira points to her own middle to show Lumo exactly where the tight feeling lives, and the Whisper Worry looks smaller. Three: Mira and Lumo look up at a ribbon of golden light showing tomorrow in order — backpack, classroom desk, and at the far end a front door with warm light spilling out. Four: Mira asleep and peaceful, the tiny Whisper Worry curled up asleep in a jar on the nightstand, Lumo dimmed to a nightlight.
OneSunday supper goes cold. The worry hasn’t found words yet — so it goes to her stomach instead.
TwoFind it: not “what’s wrong,” but “where is it?” She points. Now it has edges.
ThreeFinish it: tomorrow, all the way through — past the hard part, to the door and the ride home.
FourPark it: the worry waits in the jar till morning. It doesn’t get to come to bed.
