Our 5 Foundational Concepts



Environment + experiences shape baby’s brain.

We can’t control the genes that we inherit, but we can, to a certain degree, control the environment and experiences we have. Epigenetics is the study of how our behavior and environment change the expression of our DNA. We now know that the answer to the ‘nature vs. nurture’ debate is actually both. We are truly intertwined with our environments. By taking the steps to ensure a secure, clean, and enriching environment, we can mitigate vulnerabilities and shape outcomes.


Our brains can change!

Neuro = brain. Plastic = changeable. Our brains are malleable and shaped continuously by our experiences, and this is true for both babies and adults. Our brains are like muscles; the more we use them, the stronger they become. And how we choose to use them determines the ways they wire together.

03—Critical Windows

Months 0-36 are the biggest window of opportunity for brain development.

The window of neuroplasticity is the widest and most flexible between the ages of 0 to 3, but the window never truly closes. The brain is always neuro-flexible, and during this supercharged special window of baby’s growth, there are so many opportunities to optimize cognitive and emotional growth. Remember that raising a baby is such a forgiving process, and you don’t have to get it right from the first time, or the second, or the third - you’ll get countless opportunities along the journey.


Every thought, emotion, and action we repeat deepens neural pathways.

Baby’s brain is a network of pathways made up of neurons. When thoughts, emotions, and actions are experienced, your baby’s brain fires a neural pathway. As experiences are repeated, their brains make that pathway deeper and stronger. Neuroscientists like to say, “What fires together, wires together.”

And if you haven’t already, you may begin to notice that babies love to repeat things. This is because their brains want to create long, efficient pathways. Exciting research also shows us that babies actually learn more effectively when something is repeated.


Brains grow in the safety of routine.

Because the developing brain craves repetition and predictability, your day-to-day routine is the best framework for engaging in brain-building connected moments because this is the time that their nervous system is most calm and they are open to novel experiences. In a baby's early days, creating a predictable routine means responding to their needs in a loving and timely manner. As your baby grows, predictability and routine can also be built with an understanding of their temperament and your parenting style.

Interactive Video Lessons

The How

Interactive exercises built into everyday routines. They are meant to be simple, novel, and stimulating in a "just right” kind of way when your baby feels safe and secure. Feeling safe helps baby’s brain create deeper neural connections while they are connected with you. This is a proactive way to approach development, encouraging you and baby to connect in a meaningful way that builds critical skills and a sense of self-confidence that can last a lifetime. Each activity is also paired with a “Why?” to explain the concept and how awesome this time in diapers really is!

Our Founder's Story

“After my first child was diagnosed with a developmental disorder, I became obsessed with doing everything I could to help him - biomedically, therapeutically, and environmentally. Through the process, I’ve become aware of key developmental insights that I don’t think I would have been exposed to otherwise. On top of that, I wanted to do everything I could to ensure the neurological health of my next child. Because we had sought out the best therapies and doctors, we had special access to what could promote optimal health and development. This experience has been life-changing, and everything I’ve learned from pregnancy through the early years really makes all the difference, and my daughter is living proof as a connected, clever 7-year-old that's benefited from this knowledge. In today's world, every parent should have access to developmental guidance proactively.”
