neural development THE BIOLOGY OF BABIES where developmental science meets everyday parenting

What does the science
actually say about raising children?

Every article here draws on peer-reviewed research — from developmental biology and neuroscience to education, psychology, and child development. No trends. No guesswork. Just evidence you can actually use.

Parenting rooted in science, not trends. Drawing on biology, neuroscience, developmental psychology, and education research — this is the evidence base that helps us understand what children need and why.


Fascinating findings every parent should know

From infant neuroscience to educational psychology — here are some of the most striking things the research has revealed about child development.

1000+

Neural connections per second

In the first years of life, the brain forms over 1 million new neural connections every second — the fastest rate of any point in the human lifespan.

Center on the Developing Child, Harvard University

Language boost from conversation

Children who experience more back-and-forth conversational turns with caregivers show significantly stronger language development than those exposed to passive talk or screens.

Romeo et al., Psychological Science, 2018
90%

Brain development by age 5

By the time a child starts school, approximately 90% of their brain architecture has already been built — shaped by early experiences, relationships, and environment.

National Scientific Council on the Developing Child, 2007
25yrs

Prefrontal cortex maturity

The brain region responsible for emotional regulation, impulse control, and decision-making isn't fully developed until the mid-twenties — reframing what we expect of young children.

Steinberg, Current Directions in Psychological Science, 2005

Four concepts that change how you see childhood

Hypnobirthing: the physiology behind why it works

It's not mystical — it's the feedback loop between fear, adrenaline, and pain. Understanding it changes everything.

I'm Joanna — a former primary school teacher (trained and taught in Scotland, now back home in England), stay-at-home mum to two little ones, and someone who brings a researcher's mindset to everything, including motherhood.

I hold a degree in Ancient History and Philosophy from the University of St Andrews. When I became a mum, I brought the same curiosity to parenting that I once brought to the classroom — reading the research, questioning the mainstream, and sharing what actually holds up.

What this site is about

There's a real gap online for parenting content that takes the academic literature seriously — not cherry-picks it. Every post here draws on peer-reviewed research from developmental biology, neuroscience, educational psychology, attachment theory, and related fields. The references are always included.

I'm passionate about making this research genuinely accessible — not dumbed down, but translated. The science of childhood is fascinating, and parents deserve to know what it actually says.

How we live

We're a vegan family committed to sustainable living — cloth nappies, buying secondhand, limiting plastic. I'm also open to home education and am interested in Christianity and what it means to raise children with faith and intention.
