You learn when to go to the hospital, when to stay home and take a bath, and how to advocate for yourself when things don’t go according to plan.

They stand in the corner of the delivery room holding a water bottle, asking, "Are you okay?" (Don't ask a laboring person if they are okay.)
Then, at 3 AM during my third trimester, a wave of panic hit me. "Wait. I know how to track the baby’s size (hello, avocado week). But do I actually know how to swaddle a screaming newborn? How do I know if breastfeeding is working? What does a real contraction feel like vs. a Braxton Hicks?"
When I found out I was pregnant, I did what most of us do: I downloaded three apps, bought a stack of books, and spent way too many late nights doom-scrolling through parenting forums. I thought I was ready.
