Tamiflu, placental positioning, pitocin and SSRIs

Pitocin (a synthetic form of the hormone oxytocin) is one of the most common interventions used to start or speed up labor. And like most induction-related topics, it comes with plenty of opinions, solicited or otherwise! Here’s what we know about pros and cons from the research.

Hep B, Robitussin, and third trimester movement

Last Friday, the CDC’s ACIP announced the removal of the universal recommendation for receiving the hepatitis B vaccine at birth. This change to three-decade-old guidance has caused many expecting moms to wonder what changed, and what is the best plan for their baby.

Glucose tests, placental abruption, and the WELLS Act

If you’ve heard mixed reviews about the glucose test, you’re not alone – it’s one of the most talked about (and dreaded) parts of prenatal testing. So many moms wonder if there's an alternative to the glucola drink -- here’s what the data says about what’s available and what’s effective.

Homebirths, hot tubs, and PPD

Postpartum depression, and one treatment in particular - a new drug called Zurzuvae - have been in the news, as actress Jennifer Lawrence recently spoke publicly about her postpartum experience. It's both common and often under-diagnosed, so here’s what the evidence shows on navigating PPD.

Iron, continuous fetal monitoring, and the value of midwifery care

A popular New York Times article recently covered the practice of continuous fetal monitoring during labor, and the resulting high rate of births by C-section that we see in the US. Does CFM have any benefit, and why do we continue to do it if it so often leads to unnecessary C-sections?

COVID, retinol, and the power of a mother’s voice

Last week, a new study was published looking at COVID-19 in pregnancy, and neurodevelopmental disorders in kids. Headlines about this study have been anxiety-inducing, particularly as viruses ramp up for the season. Here’s a breakdown of the existing evidence, and what the new research tells us.

Halloween candy, cervical checks, and the postpartum ‘bounceback’ myth

Happy Halloween! With candy bowls everywhere and cravings in full swing, it’s normal to wonder how much sugar is actually okay during pregnancy, especially when everyone has an opinion on what you’re eating and drinking.

Choline, lifting heavy, and preeclampsia

We’ve all heard the exasperating and anxiety-inducing advice - “that’s normal in pregnancy… unless it's not.” Complications like preeclampsia are one of the culprits, as initial symptoms can seem innocuous - so what's actually happening in the body, and can it be prevented?

RSV protection, heartburn, and membrane sweeps

RSV season is picking up, and with both a maternal vaccine and infant antibodies available, many expecting moms are wondering which option offers the best protection for their baby -- so we dig into the data to find out.

Breech babies, disappearing symptoms, and dates

Finding out your baby is breech late in pregnancy can often lead to feelings of anxiety and concern, but there are multiple evidence-backed options for moms who find themselves in this position (no pun intended…).
