Raising healthy, happy kids shouldn't be so hard.

Learn the key to raising resilient kids, from the inside out in this groundbreaking, evidence-based guide.

Our kids are in crisis

In 2005, the New England Journal of Medicine predicted that for the first time in history, our kids are expected to have shorter lifespans than us - their parents.

20 years later, nearly 1 in 2 kids has a chronic condition.

  • Eczema: 1 in 5 kids
  • Asthma: 1 in 10 kids
  • ADHD: 1 in 10 kids
  • Autoimmunity: 1 in 13 kids
  • Anxiety: 1 in 3 teens
  • Thoughts of suicide: 1 in 5 teens
  • Attempted suicide: 1 in 10 teens
  • Completed suicides: TOO MANY

What’s the solution?

The magic is in the microbiome

Did you know that:


of your child’s immune system is in their gut


of serotonin (our “feel good” neurotransmitter) is made by your gut microbiome


of the messages sent by your Vagus Nerve are from your gut to your brain

Your child’s gut microbiome holds the key to lifelong health and resilience.

Learn Dr. Song’s proven and practical plan to:

  • Create Microbiome Magic to optimize your child’s microbiome with 5 simple steps.
  • Empower your kids so they want to make healthy choices (and you don’t have to nag.)
  • Heal your child’s gut to get to the root cause of their chronic health concerns.
  • Feel calm and confident when your kids are sick by using Dr. Song’s A-to-Z holistic pediatric guide to the top 25 acute childhood ailments.
