The Mental Load of December: Why It Feels So Heavy (And How to Lighten It This Year)

December has a very particular energy for mums. It’s festive, yes, but it also arrives with a level of ‘WTF?’ that no calendar should hold.

December has a very particular energy for mums. It’s festive, yes, but it also arrives with a level of ‘WTF?’ that no calendar should hold.

School events multiply, inboxes explode, the to-do list overflows, and the emotional load of the entire house somehow lands in your hands. If you’ve ever wondered why this month feels heavier than the rest, there’s a real psychological reason.

Let’s break it down, soften the pressure, and give you a December that feels lighter without expecting you to be everything to everyone for 21 days straight..

Why December Feels Heavier Than Other Months

The mental load = the invisible checklist in your head.

It’s the constant planning, anticipating, remembering, coordinating, and emotional holding that women tend to absorb by default.  

In December, that load spikes because…

December isn’t just busy, it’s emotionally and socially heavy.  

You’re holding your kids’ excitement, overstimulation, tiredness, and emotional ups and downs. You’re also absorbing the adult emotional climate: family dynamics, budgets, expectations, hosting decisions, smoothing tension, and keeping everything ‘nice’.

Then comes the social labour, the messages, the organising, the catch-ups, the events, the ‘bring a plate’, ‘secret sants’, the childcare logistics, the remembering, the planning, the ‘just a quick favour’ texts. The emotional and social layers of December stack fast, and they’re invisible until you’re drowning in them.

December hits hard because every timeline in your life collides at once.

School ends with concerts, class parties, teacher gifts, costumes, Christmas carols, and exhausted kids. Work deadlines suddenly sprint because everyone wants everything done ‘before the break.’ Christmas preparation adds presents, food organisation, wrapping, travel, and family logistics. And holiday planning introduces January budgets, new routines, childcare, uniforms, and schedules.

It’s four seasons of responsibilities squeezed into three intense weeks, no wonder your brain feels like it has 20 tabs open.

The Mum Myth: ‘I should be able to hold all of this’

There’s a cultural belief that mothers should carry everything from the magic, the planning, the emotions, the logistics.. and do it effortlessly.

But psychology is clear: one person cannot carry the emotional and logistical weight of multiple people and multiple seasons at once.

You’re not failing December. December is failing mothers.

From a psychological perspective, December is almost designed to overwhelm. Our working memory can only hold around 5–9 things at once, yet December demands we juggle closer to 39. 

Emotional labour activates the same stress pathways as physical strain, which is why you feel exhausted even on the days where “nothing happened.” Anticipatory stress drains your energy before you even begin, and role strain peaks at the end of the year, when you’re simultaneously the mother, the partner, the organiser, the keeper of traditions, the emotional regulator, and the creator of magic. 

All of these roles switch on at the same time and that’s why this season feels so heavy on your mind, body, and nervous system.

When you understand what’s really driving the overwhelm, everything softens because you stop carrying it blind. The real shift happens when you can spot the belief, flip the script, and ground it in one small, doable action. So, let’s walk through the big December beliefs mothers hold and reframe them in a way that feels lighter, calmer, and actually lets you enjoy Christmas too. 

1. Belief: “I should be able to hold all of this.”

Reframe: ‘This load is unrealistic.’

Action: Write down everything swirling in your head. Your brain isn’t designed to store endless tasks - paper is. When you externalise your mental load, your nervous system instantly drops out of ‘threat mode,’ because the list is no longer living in your mind on repeat. Start with a quick brain dump: every task, reminder, worry, event, and expectation that’s been tugging at you. Once it’s on paper, you can group things, delegate, simplify, and schedule them in a way that works for you.

2. Belief: “If I don’t do it, it won’t get done.”

Reframe: ‘Delegation is leadership.’

Action: Hand off one task today. Delegation isn’t a weakness, it’s a planning strategy and a form of leadership. When your list is overflowing, even removing a single responsibility creates measurable relief in your nervous system. Choose something small but impactful: order your Christmas groceries online so you’re not stuck in the Woolworths queue the week before, ask a family member to take charge of wrapping this year, or pay a friend’s teenager to do it for you. Put it on someone else’s list and let it stay there. When you share the workload, you protect your bandwidth for the things only you can do.

3. Belief: “I need to make it magical.”

Reframe: ‘Connection > perfection.’

Action: Choose one simple ritual that feels good and skip the rest.  The pressure to create a “magical” Christmas usually comes from doing too much, not from what actually matters to your kids. Pick one moment that feels meaningful, a sunset walk on Christmas Eve, a movie night with popcorn, baking one batch of cookies, or writing a note to pop in their stocking. Because when you zoom out, there’s already so much on your plate: Elf on the Shelf, advent calendars, Christmas Eve boxes, Santa sacks, gingerbread houses, the Christmas lights drive, Secret Santas, teacher gifts, student gifts, and even the annual Santa photo marathon. Let one tradition be the thing you show up for. Children remember the warmth, the energy, the way the house felt, not how many activities you squeezed in. When you simplify the season, the magic becomes easier to feel.

4. Belief: “There’s no space for me this month.”

Reframe: ‘My regular routines regulate my nervous system.’

Action: Keep your regular routines on the calendar this month. Your walk, your pilates class, your journaling, your creative hobby, whatever helps you feel like you. Treat it the same way you treat everyone else’s commitments: write it down, protect it, honour it. Even tiny pockets of consistency make December feel calmer.

5. Belief: “I’ll just push through… I always do.”

Reframe: Slowing down is strength.

Action: Practice letting something go today (and sit in the discomfort) because it will feel uncomfortable at first. Slowing down is strength, but if you’ve spent years pushing through, your nervous system will confuse “doing less” with “dropping the ball.” In reality, you’re doing the opposite: you’re showing yourself (and your kids) what healthy boundaries look like.

Choose one thing to release, the overcomplicated recipe, the extra catch-up, the handmade gifts, the event you said yes to out of guilt. When you remove even one expectation, your body can start to shift out of survival mode and into a state of presence. That’s where the real magic of the season lives.

And remember: our little girls are watching. When they see us carry everything, apologise for needing rest, and burn ourselves out to make December perfect, they learn that motherhood equals martyrdom. When they see us choose rest, boundaries, and gentler rhythms, they learn that strength is softness — and that they deserve that too.

There is no trophy for the busiest Christmas, the most magical setup, or the mum who manages Elf on the Shelf without missing a single night. The pressure to perform the season perfectly is one of the quickest ways to burn yourself out — not a requirement for creating a meaningful holiday. You’re allowed to choose ease, let go of the extras, and protect your energy. Let this December feel softer, simpler, and lighter. 

You don’t need to be everything to everyone this Christmas. You deserve to enjoy the season just as much as the people you’re carrying.  Give yourself permission to choose ease, protect your peace, and let this December feel lighter than the ones before.
