If you’ve ever been pregnant, you might remember those moments of mental fog- the ones where you walk into a room and instantly forget why you’re there, or you find yourself misplacing things far more often than usual. During my pregnancy, I lost count of how many times I misplaced my phone…
People often call this experience “baby brain,” as if it’s something to laugh off. But new science is helping us reframe it entirely. A 2024 study in Nature Neuroscience followed a woman from before conception through pregnancy and for two years postpartum, using repeated MRI scans to track her brain changes (Hepper et al., 2024). The findings show that pregnancy doesn’t dull the mind. Instead, the brain undergoes a meaningful transformation- reorganising itself to support emotional connection, bonding, and attunement with the baby.
Baby brain is not a weakness. It’s a powerful adaptation.
Your Brain During Pregnancy: Building a New Foundation
In the study, researchers observed that the maternal brain is not shrinking or deteriorating, as some myths suggest. Rather, it is prioritising what matters most as a parent: connection, sensitivity, and responsiveness. Certain areas temporarily reduce in size, while others, particularly those involved in emotional processing and social cognition, strengthen (Barha & Galea, 2017).
The Adjustment Phase: Fog, Yes. But Purposeful
During pregnancy, many people notice:
- Forgetfulness
- Slower memory
- Distractibility
- Mental “blur”
That’s totally okay- and normal. This phase feels messy, like a renovation in progress. Your brain is trimming some connections while redirecting energy elsewhere. It’s not just taking a break; it’s actively preparing you to be present and attuned to your baby.
What Emerges: A Brain Refocused on Connection
As parts of the brain temporarily reduce, other systems grow stronger. Specifically, the study observed improvements in regions supporting:
- Emotional attunement
- Empathy
- Recognising non-verbal cues
- Intuitive responding
- Bonding with your baby
In simple terms, your brain shifts from “thinking broadly” to “feeling deeply.” When we reframe baby brain this way, absent-mindedness becomes adaptation- your brain tuning itself for the relationship that matters most.
Deepening Connection, Richer Attachment
This transformation supports:
- Deeper emotional attunement
- More sensitive caregiving
- Faster recognition of subtle cues
- A stronger, more intuitive parent–baby relationship
This isn’t about returning to “normal.” It’s about becoming more responsive, more connected, and more resilient.
Holding You With Compassion & Care
At Foundations, we believe in evidence-based support delivered with warmth, authenticity, and connection. We know how powerful this kind of transformation can be- not just for parents, but for whole families.
If you’re navigating pregnancy or early parenthood and wondering whether what you’re feeling is real and whether it’s helping rather than hurting- you’re not alone. Your brain is doing something extraordinary. It’s not just changing. It’s growing into its new role.
A Gentle Reminder
When you forget where you put your phone or find yourself in mental fog again:
- Pause. This isn’t you “failing.”
- Recognise. Your brain is realigning.
- Celebrate. You’re building a deeper capacity for connection.
Baby brain is the doorway into deeper connection. Remember- you’re doing such a good job already.
