Baby Brain Is Real—and It Might Be a Superpower

Forgetting Your Coffee Again? That’s Baby Brain—And It’s Totally Normal

‍

If you've ever wandered into a room and forgotten why, or put your keys in the freezer, you’re not alone. “Baby brain,” also called “pregnancy brain” or “mom brain,” is a very real phenomenon—and no, you’re not imagining it.

The good news? It's not all bad. In fact, pregnancy brain fog might be your brain upgrading for parenthood.

‍

What Is Baby Brain?

‍

Baby brain refers to the forgetfulness, mental fog, and emotional shifts that many women experience during pregnancy and postpartum. Common baby brain symptoms include:

• Memory lapses (names, appointments, where-you-put-your-phone situations)
• Difficulty focusing or multitasking
• Increased emotional sensitivity
• Feeling mentally slower than usual

These changes aren’t just due to exhaustion—though lack of sleep definitely plays a role. Your brain is actually changing.

The Science Behind Pregnancy Brain Fog

‍

Studies using MRI scans have shown real structural changes in the brains of pregnant women, especially in areas tied to social cognition and emotional regulation. One groundbreaking study found these changes can last up to two years postpartum.

Why? Your brain is remodeling itself to help you bond with, protect, and respond to your baby. This includes:

• Shrinking in areas related to self-focus and expanding areas tied to empathy
• Hormonal surges (estrogen, progesterone, oxytocin) that affect cognition
• Sensory attunement so you notice even the tiniest baby cues
• Prioritization of baby-related stimuli over everyday distractions

It’s not memory loss—it’s reallocation.

Does Baby Brain Happen to Dads Too?

‍

Sort of. While not identical, “dad brain” is real, especially in involved fathers and non-birthing partners.

Research shows that when dads take on caregiving roles, their brains also shift—particularly in areas related to empathy, emotional processing, and vigilance. The more time spent caregiving, the stronger the changes. In fact, a 2022 study found that new fathers experience structural brain changes in the cortex similar to those seen in birthing parents—though typically to a lesser degree.

Translation? Dads and partners might not experience pregnancy brain fog, but the transition into parenthood rewires everyone.

How to Support Your Baby Brain (Without Losing It)

‍

Here are five ways to care for your brain during pregnancy and early parenthood:

1. Prioritize sleep (or at least naps!)
2. Eat brain-boosting foods—think salmon, leafy greens, nuts, and whole grains
3. Move your body regularly—even short walks help improve mental clarity
4. Write it down—apps, sticky notes, and shared calendars are lifesavers
5. Lower your expectations—this is a transformation, not a test

‍

Baby Brain Is Not a Bug—It’s a Feature

‍

You’re not “losing your mind.” You’re evolving into someone new. Yes, the fog is real—but so is the superpower. Your brain is becoming more attuned, responsive, and emotionally intelligent.

You may forget what day it is, but you’ll never miss your baby’s cry.

At Villie, we honor that transformation—and support you through all of it.
