Tips and Tricks

What is baby brain? Is it a myth, or is there some truth to it?

Many new mothers experience it: The keys are in the fridge, the child's birthday is suddenly hard to remember, or the middle of a sentence vanishes into thin air. The phenomenon is popularly called "baby brain," but is it just a poor excuse for sleep deprivation, or is something actually happening physically in the brain? Research shows that there is far more substance to the concept than previously thought.

3 quick facts about baby brain:

  • Specialization: Your brain is restructured to make you an expert in your child's needs.
  • Not just breastfeeding: The changes are seen in all parents (including fathers) due to the caregiving role.
  • Shift in focus: You forget little things because the brain prioritizes the child's safety above all else.

The science behind: What happens in the brain?

According to research (described by, among others, Videnskab.dk), "mommy brain" is not a sign that one is becoming less intelligent. On the contrary, a fascinating restructuring takes place.

Studies show that the amount of grey matter in certain areas of the brain decreases during pregnancy and in the period after birth. This may sound alarming, but researchers compare it to the process that occurs during puberty: the brain is "tidying up" and fine-tuning neural networks. The purpose is to make the mother (or father) more sensitive to the child’s social signals and needs. It is, therefore, a form of "biological upgrade" for parenthood.

Why does it feel like forgetfulness?

Although the brain becomes specialized in caregiving, it often comes at the expense of "non-vital" functions for a period. When your focus is 100% directed toward the child's survival and well-being, there is less bandwidth for remembering flea markets or grocery lists.

In addition, there are the factors we all know:

  • Sleep deprivation: The greatest enemy of memory.
  • Oxytocin: The "love hormone" helps with bonding, but can also have a slightly dulling effect on short-term memory.
  • Mental load: As a mother, there are often 1,000 tabs open in your head at the same time.

5 tips for dealing with "baby brain"

Although "mom brain" is a natural process, it can be frustrating in everyday life. Here is what you can do yourself:

  1. Write it down: Use a physical notepad or your calendar with reminders. Your brain needs to be unburdened from practical information.
  2. Fluids and energy: The brain uses enormous amounts of energy – especially if you are breastfeeding. Make sure to drink plenty of water throughout the day.
  3. Utilize small breaks: It sounds like a cliché, but even 10 minutes with your eyes closed can help your brain reset.
  4. Fresh air: A walk with the stroller provides oxygen to the brain and can reduce the feeling of "brain fog."
  5. Be kind to yourself: Accept that this is a transitional phase. Your brain is busy performing the most important task of its life: bonding with your child.
