“…a clearly explained and reassuring guide from an expert in the field.”

–Publisher’s Weekly


As parents we always want the best for baby, but we also need to sleep.

Which factors actually matter when it comes to baby sleep? Teething? Mattress quality? Weight? Science has the answer to that. We can use knowledge about

our biology,

our internal body clock, and

the fundamentals of sleep

to help babies sleep. When my kids were born, I had worked for 3 years in a laboratory researching sleep. We only use red light when we don’t want to wake up our animals. Naturally, I got red light bulbs for my kids’ rooms. It worked so well that I starting thinking about other insights from sleep research that might help me get my kids to sleep through the night. I found clear research results and formulated a simple 3 step method to help babies sleep. Next I started working with real parents to see if it worked with babies of different ages, backgrounds, and sleep problems and was so successful that I decided to bring my method to the broader public by teaming up with one of the largest publisher in the United States, Simon&Schuster. My groundbreaking baby sleep book, How Babies Sleep – the Gentle, Science-Based Method to Help Your Baby Sleep Through the Night, is available now for pre-ordering at Amazon and in bookstores nationwide in May 2020.

The How Babies Sleep Method

Why this method?

There is a lot of advice on baby sleep out there, but it’s hard to decide, which one is the best. I am a sleep researcher and have distilled 100 years of sleep research into 3 simple steps:

  1. Blue and white light as in daylight and regular light bulbs suppress sleep – and young children are particularly sensitive. Get red light bulbs to help baby sleep at night.
  2. Baby’s naps are ever-changing, but by knowing how to adjust them, you can help baby sleep at night.
  3. I have developed a research-based gentle sleep training effective from 3 months – 5 years to help your baby, toddler or pre-schooler sleep through the night.


My mission is to help babies – and adults! – sleep better – using cutting edge sleep research.
