Mommy brain: where does it come from and how to deal with it?

You walk into a room... but why? Your coffee goes cold on the counter while you look for your phone... which is in your hand. Welcome to the era of mommy brain! This mental fog, which makes you forget the simplest things, affects almost all new mothers. But is it just fatigue or is there another reason behind these memory lapses? Spoiler alert: your brain isn't regressing, it's evolving. And you're about to understand why.

What is mommy brain?

Mommy brain, or mom brain, refers to the feeling of mental confusion that many new mothers experience during their postpartum period. They experience small memory lapses, such as: losing their keys, forgetting an appointment, searching for a word mid-sentence... In short, this "mushy brain" feeling can be funny (or annoying!). However, it's a widely shared reality.

Sleep is often blamed as an aggravating factor for this phenomenon. Not at all! Because it's not the only cause. Mommy brain is primarily a natural adaptation of the maternal brain to its new condition. It transforms to better meet the baby's needs, particularly by improving parental instinct and emotion management.

Its cause? Changes in mothers' brains

Neuroscience studies show that motherhood leads to a real transformation of mothers' brains. For example, research published in Nature Neuroscience observed a reduction in gray matter volume in pregnant women. Primarily in areas related to social cognition and empathy. This remodeling does not equate to a loss of abilities, but to a kind of temporary recalibration: the mother's brain specializes to better understand and respond to her baby's needs.

Hormones also play an important role in this story. Particularly oxytocin, released in large quantities after childbirth (and also during the third trimester of pregnancy). This promotes mother-child bonding and influences attention to the baby, sometimes at the expense of certain daily tasks.

So, even if these transformations are destabilizing, they are still important! Because they allow new mothers to be more attentive and responsive to their child's signals.

 

Why do we forget the pain of childbirth?

Childbirth is often described as one of the most painful moments in a woman's life. However, many mothers find that with time, this memory fades. Strange, right? Not really.

Let us explain: during childbirth, the body releases a large amount of oxytocin and endorphins, two hormones with analgesic effects. Their talent? Helping us to bear the pain at the time. And to forget this suffering, little by little.

The mother's brain also ends up remodeling itself: certain areas linked to stress and memory change during the postpartum period. When we tell you that nature is well-designed...

Finally, this phenomenon also plays out on a psychological level. Because a selective forgetting mechanism allows mothers to focus on the positive aspects of birth. Which, consequently, facilitates the desire to have other children.

How long does mommy brain last?

Good news: mommy brain is not permanent! While the first few weeks postpartum are often marked by intense mental fog, most mothers gradually regain their normal cognitive function.

Nevertheless, it can persist for up to two years after childbirth. Why? Because it's 24 months after birth that the baby begins to gain significant autonomy. This lightens the mother's emotional burden.

That being said, let's keep in mind that everything also depends on the context. Because lack of sleep, stress, and mental load can prolong this feeling of confusion. The quality of sleep, for example, plays a super important role in recovery after pregnancy. And we know how rare full nights of sleep are for new parents!

Our tips to make your life easier if you are affected by mommy brain

While waiting for everything to return to normal, here are some tips to better manage mommy brain in your daily life.

1. Write everything down

With fatigue and mental load, it's easy to forget an appointment or an important task. Using a note-taking app on your phone or a notebook to write everything down can be a solution: shopping lists, dates, and all the little things not to forget.

2. Sleep whenever possible

We repeat: sleep plays an important role in cognitive recovery. So, even if full nights are a distant memory, try to take micro-naps when the baby is sleeping.

3. Trust your brain

Even if you feel more distracted, your brain isn't regressing, it's adapting! This reorganization makes you more receptive to your baby's needs, so be kind to yourself.

4. Accept to delegate

Mental load can amplify the feeling of confusion. So, if you can ask for help from those around you... Do it without hesitation, to lighten your daily life.

In short, even if mommy brain is a scientifically proven reality, it is far from being a sign of weakness. On the contrary, it reflects an incredible adaptation of the brain to motherhood. So, if these small forgetfulness and mental fog can be unsettling, remember that they are temporary and part of a natural process! With time, better sleep, and a bit of organization, everything will fall into place. In the meantime, be kind to yourself: your brain hasn't lost its capacities, it has simply adjusted to your new life as a mom.
