What a Free Grandparent Actually Costs

Marisol’s mother arrives at 6:50 in the morning, four days a week, and lets herself in with a key she has had for six years. She makes the school lunches. She does the drop-off for the older one and keeps the younger one until 3. She has done this since 2020, when Marisol went back to work full time and the arithmetic of daycare for two under three did not survive contact with a spreadsheet.

In Marisol’s household budget — which is thorough, and which she showed me — the line for childcare reads $0.

This is the largest untracked transaction in the American household economy. Grandparent care is the second most common childcare arrangement in the country, behind parental care and ahead of licensed centres for children under five. It has no invoice, no contract, no notice period, no complaints procedure and no price. It is described by everyone involved, with total sincerity, as free.

It is free the way a family loan is free.

The three currencies

Across four households and five months, what people paid was consistent enough to name.

The first currency is the grandparent’s own plans. Two of the four grandparents in this piece had explicitly deferred something — one a move to be nearer a sibling in Arizona, one a part-time job she had liked — and neither had said so to their adult child. Both told me in the first interview, unprompted, within about twenty minutes. Both asked me not to raise it with their daughter. One eventually raised it herself, eleven weeks later, after her daughter read an early draft of this article and asked her directly.

The second currency is the adult child’s standing to set terms. You cannot easily tell someone how to handle screen time when they are handling it for free. Three of the four parents described a version of this: a rule they had wanted, and had not asked for, because the asking felt disproportionate to the gift. Sugar, in two cases. Church, in one. Screen time in all three.

The third is the silence that grows over both. Nobody in any of these households had discussed what happens when the arrangement ends — including the version where it ends by a parent moving in. Three of the four had never discussed an end date at all.

What breaking looks like

The arrangement in this piece that ended, ended in a hospital corridor in March.

Dennis, 74, had been doing three days a week for his son’s two children for four years. He fell in his own kitchen on a Tuesday, fractured a hip, and was in surgery by the evening. The family absorbed, in the space of about six hours, an elderly parent’s medical emergency — the afternoon Anna Kowalczyk describes in The Discharge Call Nobody Prepares You For — and the total collapse of its childcare, and had to make decisions about both while doing neither well.

His son said something to me a month later that I have not been able to put down. “We spent four years never talking about what would happen if he couldn’t. And then we had eleven minutes.”

This is the specific cost of the arrangement having no terms. The health event was going to happen or not happen regardless. What the absence of an agreement did was guarantee that the childcare crisis arrived stapled to it.

The households that wrote it down

The fourth family did something none of the others had done, and did it for an unromantic reason: the grandmother had been a union steward for nineteen years and did not believe in undocumented arrangements.

Their agreement is one page. It names the days and the hours. It names a figure — $200 a week, well below market, which both sides describe as symbolic and neither describes as nothing. It names two weeks’ notice on either side, and it says, in a sentence that took them three attempts to word, that either party can end it without giving a reason.

They review it in January. The review takes about twenty minutes and, the daughter says, is boring, which she has come to understand is the entire point.

That family has had two hard conversations in four years: one about the money going up, one about a summer the grandmother wanted off. Both were scheduled. Both were short. Neither was a crisis, because the thing being changed was a document rather than a relationship.

The number nobody has

None of this argues against grandparent care. Every family in this piece would make the same arrangement again, including Dennis, who told me from a rehabilitation facility that the four years had been the best of his retirement and that he intended to be back by autumn.

It argues against pretending it is free. A household that runs a $0 line for its largest childcare arrangement has not saved the money. It has moved the cost somewhere it cannot see it: into a 74-year-old’s deferred move to Arizona, into a mother’s unraised rule about screens, into the eleven minutes in a corridor.

Put it on the page. Give it a number, even a small one. Give it a notice period, which is the part everyone finds mortifying and which is the part that works. An arrangement written down can be changed. An arrangement that was never written down can only be broken.
