Eleven forty on a Saturday night, and I am standing in Dana's kitchen counting nine paper tickets into a Tupperware lid while her husband fixes me a ginger ale I did not ask for. The tickets are orange index-card strips, each stamped with a lopsided potato, which is the co-op's official seal cuz my wife carved it into a linoleum block in 2023 and nobody has topped it since. Each strip is worth thirty minutes of babysitting. Three hours with two kids asleep upstairs runs nine strips, eleven forty to two forty, plus a verbal guarantee that the guinea pig gets lettuce at seven.
Before the co-op, a Saturday out cost real money. A sitter for our two runs $18 an hour cash thru the Care.com listing we have used since 2022, so a three-hour dinner plus tip lands at $58 before the dinner itself, and in February of the co-op's first year we had spent $174 on sitting alone. Fourteen families were doing versions of that math every month, all of us within a mile of each other. Dana put a stop to it with a cigar box.
No cash moves in this economy, ever, and that fact has opinions attached to it from a CPA and, briefly, the entire extended family group chat. It also settled an argument that had been building since September, which I will get to, because the argument is the reason the box works at all. But first, the potato.
how the box got built
March 2023: Dana's sitter cancelled forty minutes before a work gala, and she spent the evening calling nine houses til mine picked up. The next week she had all of us over with a Google Doc titled CO-OP RULES v1 and a wooden cigar box holding 280 strips. Fourteen families signed that night. Two pages of rules, one page more than we have needed since: everyone starts with 20 strips, sitting earns 'em, goin' out spends them, and the secretary keeps the ledger.
the secretary and the notebook
The secretary rotates monthly and keeps a spiral notebook that has outlived two shared spreadsheets, cuz people quietly edit spreadsheets and nobody argues with Nadia's handwriting. Booking happens in the group text: date, hours, kids' bedtime, strip count. The secretary squares it all Sunday morning with a photo of the ledger page. March's secretary is a guy named Phil who stamps the corners like postage and refuses to explain why.
the Mendozas hold forty-one
The economy has weather now. The Mendozas sit constantly, both teachers, summers free, and they hold 41 strips, the richest house in the co-op by a factor of three. The Parks sit at 2 and cannot book a Saturday til they sit, which is by design and not punishment. Weekend nights cost more: a Saturday prime time runs 3 strips an hour, a weekday evening 2, and one New Year's Eve went for 6 an hour and was worth every single one.
the fall blowup
Here is the argument. One family booked four Saturday nights in a row thru the fall and sat exactly once since September, and the ledger page told on them: fourteen nights out, one night in. The group text went cold for about six hours, which among fourteen adults who otherwise like each other counts as a blizzard. The fix came from Dana, and it was boring and perfect: the floor. Nobody books while holding fewer than 5 strips. The family sat two weekends in a row and the temperature came back before Thanksgiving.
what our CPA said
At some point Marcus asked the question out loud: if we are all gettin' babysitting, is any of this taxable? We took it to our CPA, a patient woman named Dougherty who has done our returns since 2019. Her answer, trimmed: a non-cash co-op where families reciprocally exchange sitting generally produces no reportable income for anyone, because no one is paying anyone. Then she flagged the flip side hard. The child care tax deduction, the dependent care credit, requires real payments to a provider with a tax ID or Social Security number and a Form 2441, and strips in a Tupperware lid qualify for none of it. If we ever want the credit, we pay cash and paper it. We ran the numbers both ways and the strips still won.
the nine days at the lake house
August 2024, the box almost died. Phil took the cigar box on a family lake trip cuz he was secretary that month, left it in a cabin, and the cabin was not his, so the box spent nine days locked in a stranger's Airbnb in Door County. Fourteen families ran on scrip, torn napkin corners initialed in pen, and Nadia reconciled the whole mess in one evenin' with the ledger and a long sigh. The strips came home wrinkled. Nobody trusts Phil with the box in August, permanently.
why nobody quits
The arithmetic is why. Fourteen families, call it two Saturday nights out a month each, at $58 a night cash is $19,488 a year of babysitting that gets done anyways, by people who were mostly goin' to be home. Nobody says that number out loud. What gets said is slight: Priya's orthodontist got paid, the Mendozas got a standing Friday, and nobody has cancelled on a gala in three years.
back in Dana's kitchen
Dana walked me out at two forty-five and handed back three strips because the kids had been asleep since ten and the lettuce got done at seven sharp. The Tupperware lid went back in the box and the box went on top of the fridge, next to the vitamin bottle nobody uses. Eleven forty to two forty-five. Nine strips, three returned. That is it. That is the whole currency.
