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.

Even for the most body-secure among us, gaining anywhere from 20 to 40 pounds during pregnancy is no picnic. Sure, we have days where we are full of energy and glowing and ready to flaunt our adorable baby bumps. But we also have days, especially in the third trimester, where we feel less like mama-goddesses and more like sweaty, frumpy, nothing-fits-anymore messes.
To take the edge off, I turned to the Institute of Medicine’s (IOM) report on pregnancy weight gain, which provides the evidence base for their widely-referenced weight gain guidelines:
- Underweight: Gain 28-40 pounds
- Normal weight: Gain 25-35 pounds
- Overweight: Gain 15-25 pounds
- Obese: Gain 11-20 pounds
Some of what I learned from their report was outright reassuring, like that a sudden bump up in weight in the second trimester is common and does not imply that you will continue to gain weight at a fast clip. Other facts, like that 15-30 percent of the fat gained during pregnancy goes straight to our thighs, were less reassuring. Continue reading Five little known facts about pregnancy weight gain
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.

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.

Too little iron in infancy can cause irreversible cognitive deficits. And iron deficiency can have no symptoms. It’s scary.
Yet the advice parents receive about their baby’s iron needs is complex, conflicting, and incredibly confusing.
