His Father’s Phone Was Also On. It Did Not Ring.

Load · The Reading Room, Vol. 110 · 8 min read · what a survey of 3,000 parents found about who holds the list, and why the role outlives the school run

The default parent is the one whose phone rings first. The school, the doctor, the child with the flat tyre at 11 p.m. It is supposed to be a phase of early parenthood. For many women it has now lasted twenty-five years, and a large 2024 survey of US parents measured why it lands where it does.

The short answer: the default parent is the one who, without any explicit agreement, holds primary responsibility for noticing, planning and responding to children’s needs. A 2024 study of 3,000 US parents found mothers carried 71% of the household’s cognitive tasks against fathers’ 45%, and 79% of the daily, routine ones.¹ The role forms around that daily work, and the daily work does not stop when children grow up.

Your son is twenty-two. He lives two hundred miles away, has a job and a car and a flat with a lease in his own name. At 11:14 on a Wednesday night your phone lights up, because the car has a warning light on and he would like to know what it means. His father is sitting beside you on the sofa. His father’s phone is also on. It does not ring.

Nobody decided this. There was no meeting at which the role was assigned. It simply accumulated, one school form and one sick day at a time, until you became the parent everyone calls first, and it turns out that the role has no retirement age.

What is a default parent?

It is the parent who handles children’s needs by default: the one the school contacts, the one who knows the dentist’s name, the one who notices the permission slip and the growing feet and the friend who has not been mentioned lately. The other parent may be loving and involved. The difference is that the default parent does not wait to be asked, because the system assumes she is already on it.

The term is informal, and the research uses other language, usually “cognitive labour” or “mental load.” But the measurements below describe the same thing from the inside: who does the thinking that makes the doing possible.

What did the research on parents’ mental load find?

The largest recent study is by Ana Catalano Weeks of the University of Bath and the sociologist Leah Ruppanner of the University of Melbourne. They surveyed 3,000 US parents about who carries the cognitive work of running a household with children.¹

Mothers handled 71% of household tasks that required mental effort. Fathers handled 45%. The two figures overlap, because some tasks were being handled by both parents.¹ The gap was widest in the daily, routine work, the meals, the schedules, the constant low-level tracking: 79% for mothers against 37% for fathers.¹

Fathers took the lead on episodic tasks, the occasional ones such as finances and home repairs, at 65%. Even there, mothers were handling 53%.¹ In other words, the categories men were more likely to own were ones women were often doing as well.

An older Pew Research Center survey of dual-earner, two-parent households points the same way. Asked who does more of managing children’s schedules and activities, 54% of parents said the mother and only 6% said the father. Among mothers themselves, 64% said they did more; fathers were more likely to say the work was shared equally.²

If the phone that always rings first is one line on a much longer list of things you hold without anyone counting, the Quiet Audit does the counting in ten minutes, on one page. Start here.

Why am I always the default parent?

Because the role follows the daily work, and the daily work was yours first. In the Weeks and Ruppanner data, the biggest gap was in routine, everyday tasks.¹ Those are the tasks that generate knowledge: if you pack the lunches, you know who stopped eating tomatoes. If you know that, you are the natural person to ask. Every question you answer makes you the more natural person to ask the next one.

There is a perception gap on top of that. Both studies found fathers more likely than mothers to describe the load as shared.¹ ² That gap matters, because a problem one partner does not see is a problem that cannot be negotiated. A great deal of the work of the default parent is invisible precisely because it is the work of noticing, and noticing does not leave marks.

Why hasn’t it stopped now my children are older?

Because nothing in the arrangement was ever tied to the children’s age. The role was built on knowledge and habit, and both persist. Your adult children call you because you have always known the answer, and because calling you has always worked.

For many women in their fifties, the default parent role has also quietly expanded upward. The same competence that made you the first call for the school now makes you the first call for your own parents’ appointments and medications. We look at that double load in what the sandwich-generation research found about women in their fifties, and at the specific pull of grown children in it didn’t stop at eighteen, it was never going to.

The study did find one telling contrast. Single fathers took on substantially more of the mental load than partnered fathers did.¹ When there is nobody else to be the default, men do it. The capacity is there. The arrangement is what decides whether it gets used.

It is worth naming what this costs, because the cost is easy to file under “just how things are.” Being first contact means never being fully off. Every evening has a phone in it that might ring. Every holiday has a school email that might need an answer. None of it takes long. All of it takes attention, and attention held open for twenty-five years is not a small thing to have given.

How do I stop being the default parent?

Not by announcing it. By changing where the first call goes, one domain at a time, in a way that does not depend on anybody remembering.

The practice takes about five minutes. Pick one area: the school or college, the dentist, the car insurance for the child who drives, the sports club. Log in or phone, and change the first contact to the other parent. Then tell the other parent, once, plainly: “You’re first contact for the dentist now. I’ve changed it with them.” That is the whole move.

It works because it changes the system rather than asking a person to change a habit. The dentist does not know about your twenty-five-year history. It simply rings the number at the top of the list. The first few calls will feel strange, and you will be tempted to take them back. Let them run. With adult children, the equivalent sentence is gentler: “Try your dad first on car things. He’s better at it than I am.” Sometimes that is even true.

Underneath the phone calls sits the larger pattern of invisible work, measured and named in our guide to the mental load and why it lands where it lands.

Questions women actually ask about this

What does default parent mean?

It means the parent who handles children’s needs by default, without an explicit agreement: the one contacted first by schools and doctors, and the one who tracks schedules, supplies and worries. It is an informal term for what researchers call the cognitive labour or mental load of parenting.

What is default parent burnout?

It is the exhaustion that builds when one parent carries most of the noticing, planning and responding for years. Research found mothers handled 71% of household cognitive tasks against fathers’ 45%.¹ When that load runs alongside a demanding job, the three signs of burnout, exhaustion, detachment and a sense of futility, can follow.

Why do schools always call the mother?

Often because she is listed first, and she is listed first because she filled in the form. Schools follow the contact list. Changing the order of contacts is one of the simplest ways to move part of the default role to the other parent.

Does the default parent role end when children grow up?

Not automatically. The role is built on knowledge and habit, and adult children tend to keep calling the parent who has always had the answer. It often expands to include ageing parents as well, which is why women in their fifties frequently describe the load as heavier, not lighter.

Do fathers see the imbalance?

Less often. Both the 2024 study and Pew’s survey found fathers more likely than mothers to describe the division as equal.¹ ² A load that one partner cannot see is hard to renegotiate, which is why changing the system, such as contact lists, can work better than arguing about fairness.

On the research. Both studies rely on parents’ own reports, and the 2024 study measured perceived responsibility rather than hours. Neither focused on parents of adult children, so the section on older children is a reading of the mechanism, stated as one. The Pew figures date from 2015.
