The mental load of motherhood: what is it, and how do you share it?

Short answer: The mental load is the invisible work of running a family: noticing what needs doing, planning, deciding, remembering and checking that it got done. Research shows mothers often carry more of this cognitive work than partners, and that a heavier share is linked to more stress and burnout. Sharing it means handing over whole responsibilities — including the thinking — not just individual tasks.

What is the mental load?

Think of the difference between buying the birthday present and remembering the party is on Saturday, checking whether you replied, knowing what your child would like, and noticing that the card is still in your bag. Sociologist Allison Daminger describes this “cognitive labour” as four steps: anticipating needs, identifying options, deciding, and monitoring progress.

What research shows

In interviews with 35 couples, Daminger (2019) found that women did more cognitive labour overall, and especially more of the anticipating and monitoring.
In a 2024 study of 322 mothers of young children, mothers' share of cognitive household labour was even more unequal than their share of physical chores, and a heavier cognitive load was associated with more depression, stress and burnout, and lower relationship functioning.
In a 2019 study of 393 US mothers, most reported that they alone were responsible for organising family schedules and keeping order at home, and feeling disproportionately responsible was linked to strain on their wellbeing and lower relationship satisfaction.

These studies show associations, not proof that the mental load causes these problems. They do confirm what many mothers feel: the invisible work is real work.

Signs you're carrying too much

You're the default person for every question: “Where's the…?”, “When is…?”
You lie awake running through lists.
Help feels like more work, because you have to explain and check everything.
You feel irritable, flat or “touched out”, with no space in your head for yourself.

How to share it — practically

Make it visible. For a week, both write down everything you notice, plan, remember and do for the family. Seeing it on paper changes the conversation.
Hand over whole responsibilities, not tasks. Not “can you buy nappies?”, but “you own nappies and wipes: noticing when they're low, ordering, and making sure we never run out.”
Let go of the method. If your partner owns it, they decide how. Different isn't wrong — and redoing it pulls the load back to you.
One shared system: a shared calendar and one shared list both of you add to and check.
A short weekly check-in (15 minutes): what's coming up, who owns what, what's slipping.
Lower the bar where you can. Not everything needs to be done, or done perfectly.

If you're doing it alone

Single parents and mothers with little support often can't hand over. Focus on reducing the load instead: simpler routines, repeating meal plans, batching admin into one slot a week, and asking specific people for specific help. See single motherhood.

When it's more than overload

If you feel low most days, can't enjoy anything, feel hopeless or that you can't cope, or have thoughts of harming yourself, please talk to your GP, midwife or health visitor. Postnatal depression can start any time in the first year after birth. If you are in crisis, contact emergency services or a crisis line in your country — for example Samaritans on 116 123 (UK and Ireland), 988 (US) or 113 (Netherlands).
