The First 1000 Days shape a lifetime
From conception to a child's second birthday, the brain is built at a pace it will never match again, setting the stage for how your child learns, thinks, and feels.

Every parent wants the best for their child's future. Turns out, the brain is the kind of thing that makes that happen. Yet, most vitamins are missing what your child needs.
The Brain Building Stages
Intro
Your child's brain is 80% built by age two
From the start of pregnancy through age two, your baby's brain forms more than 1,000,000 new connections every second. Each stage shapes a different part of the brain and needs different nutrients to do its work.
Pre-pregnancy
Prepare
·Day -90 - Day 0The mother builds reserves
Great brains start with the right building blocks
Your baby's spinal cord finishes forming by Day 28 before most women know they're pregnant. That's why the 90 days before you become pregnant matter. Your body is already building the reserves your baby will draw from first: methylfolate, choline, DHA.

·Day 1 - 280Parietal lobe: the architecture gets set
The brain is building 250,000 neurons every minute
All those kicks and flutters? Inside, something bigger is happening. Your baby's brain is forming its basic structure - the part that will one day help them feel a hug, know their body, and make sense of the world. Neurons are finding their places. The outer brain is folding to fit more power into less space.

·Day 281 - 645Temporal lobe: language & memory
The brain makes 1,000,000 connections every second
Every time your baby hears your voice, follows your face across the room, or reaches for a toy, their brain is building new pathways. The temporal lobe is the part of the brain that helps with language and memory. And inside it sits the hippocampus, the brain's memory center, and it's growing faster right now than it ever will again. Every lullaby, silly face, and every time they hear their name is wiring the brain for what comes next.

·Day 646 - 1000Prefrontal cortex: emotions & self-control
The circuits come online
First words turn into sentences. A toddler starts figuring out how to wait, share, and calm down. That's the prefrontal cortex still being built. The brain is also pruning: keeping the pathways your child uses most, trimming the ones they don't. Every new word, every tested "no," every bedtime routine shapes how this part of the brain takes form.
Beyond
Cerebellum: coordination & learning
Keep building on top of the foundation
From wobbly first steps to running and holding a crayon, the cerebellum keeps growing well past the second birthday. A layer called myelin is wrapping around the neural wiring laid down during the First 1000 Days, helping signals travel faster and more clearly. Every dance, every tumble, every scribble is built on the foundation you already gave them.
Meet the Neurologist Who Demanded More
Board-certified neurologist. Mom of two. She'd spent her career studying the brain.
When Mika got pregnant, she went looking for a prenatal and came up empty. Every formula she found was built for the body, on decades-old science.
"Good enough" wasn't good enough for the brain.
So she built Mama Bird: A vitamin system designed for the most important window of brain development and beyond.

The best time to start is now
The brain your child will carry for life is being built right now. The only question is when you start.
