Introducing Solids and Baby Sleep: Yep, Early Solids Improve Baby Sleep After All

Don’t give your baby solids until 6 months of age. This is the unambiguous advice of the world’s most highly regard medical organizations, including the American Academy of Pediatrics, the UK’s National Health Service, and the World Health Organization.

Or so we have been told.

Sign away mamas: Formula consent forms are based on unscientific fearmongering

As part of their “baby-friendly” initiatives, some hospitals now require women to sign consent forms before receiving formula. These forms purport to list the “harms” associated with “a single bottle” of formula, and ask that parents signify their understanding that formula should not be given unless medically necessary.

On its face, asking parents to sign a waiver to receive formula, a long-used and widely available way of feeding babies, seems astoundingly paternalistic. But what I find most shocking are the allegedly “scientific” claims these forms make about supplementing with formula.

What’s the deal with the infant microbiome?

The human microbiome is one of the hottest topic in medical research today, and with good reason.

This collection of trillions of microscopic inhabitants–bacteria, viruses, and fungi—cover nearly every interior and exterior surface of the human body, and many scientists now believe that these unseen co-passengers, far from being incidental hangers-on, are instead actively cultivated by our bodies and play a critical role in our immune and metabolic health.

Over the last decade, studies have linked the composition of our microbiomes the to a panoply of modern ailments: obesity, asthma, allergies, acne, C difficile induced diarrhea, and autoimmune diseases like Crohn’s and Type 1 Diabetes.

Our microbiome may matter most in early infancy.

Prenatal Testing: Download my ebook (free)!

Who needs prenatal testing for genetic disorders? How much does your risk of carrying a baby with a genetic disorder increase with your age? Which prenatal test or screen is right for you?

These are among the questions my amazing co-author Molly Dickens (and fellow pregnant scientist blogger/partner-in-crime) and I tackle in our new ebook on prenatal testing. We provide a quick “cheat sheet” on how these tests compare, and then dig into the nitty-gritty details of each as well as the history of prenatal testing and how to estimate your personal risk of carrying a baby with a genetic disorder.

Even having gone through prenatal testing twice before, I was still surprised to learn while researching this book that…

  1. Testing only women over 35, as was the case in the 80s and early 90s, misses around 70% of the cases of Down’s Syndrome.
  2. The risk of miscarriage from amnio and CVS is around 1 in 1000–far, far lower than the still commonly cited but outdated 1 in 100 estimate.
  3. Until you are 38 years old, you are more likely to carry a baby with a chromosomal disorders involving tiny pieces of chromosomes than carry a baby with disorder involving missing or extra whole chromosomes–but these disorders are not well detected by any prenatal screens. This is a huge problem, because younger women are often advised to get screens over diagnostic testing.
  4. How women under 35 are more than twice as likely to get a false alarms on prenatal screens as women over 35.

And so much more that I am excited to share.

We all need to up-to-date, evidence-based information to make the best decisions for us and our families. But with prenatal testing rapidly evolving, sometimes doctors and other healthcare professionals are woefully behind or outright misinformed on the latest developments. So please download and share with fellow parents-to-be!
