About Brighter Days, Darker Nights and Nikko Kennedy

Hi, I’m Nikko.

My mission is to improve the way we welcome babies into the world.

My domain is addressing circadian disruption in pregnancy, the birth suite, and postpartum.

This publication is for parents, practitioners, and maternity care leaders who are also ready to make a different for the next generation.

If that’s you, ready to become a beacon of light-based wellness—welcome! I’m so glad you are here.

Brighter Days, Darker Nights is a reader-supported publication by consultant, doula, and educator Nikko Kennedy.

“My go-to source for pregnancy & women’s hormones from the Circadian lens.”

— Sarah Kleiner, Board Certified in Applied Quantum Biology, host of Evolving Wellness Podcast

Why subscribe to Brighter Days, Darker Nights?

Read this because it’s unlike what you will read about maternal and family health anywhere else, including in the circadian and quantum biology wellness spheres.

I don’t do generic wellness, biohacking, or pop-circadian content and I don’t hold back the details when I think they are important.

The resources I publish here are specific to women, the perinatal years, and the wider arc of life that surrounds it including raising children and teens, navigating menopause and supporting elders with chronic conditions including cancer and dementia.

I pepper my writings with peer-reviewed citations as well as my pragmatic experience as a mother to many and longtime birth professional.

So… is it a mom blog or is it a professional resource?

It’s both, and if this is for you, you are also a multifaceted individual curious about many things and ready to grow in your own light.

“At last, somebody within the quantum biology community acknowledging the ‘Willy nilly’ use of the term quantum! Read Nikko. It’s a re-education in itself. So refreshing!”

— Nathan Riley, MD, FACOG, Born Free Method
