First Trimester Guide for Dads

The first 13 weeks are a crash course in pregnancy. Your partner's body is doing extraordinary work, most of it invisible. Here's what's actually happening week by week, and what you can do about it.

What to know about the first trimester

What happens this trimester

Your baby goes from a cluster of cells to a 3-inch fetus with a heartbeat, fingers, toes, and early facial features. All major organs begin forming in these first 13 weeks.

Dad's role

This is your onboarding period. Learn the terminology, attend the first ultrasound, handle the logistics of choosing a provider, and be the steady presence while your partner navigates morning sickness and exhaustion.

Things to prepare

Review your health insurance coverage, start a baby budget, research prenatal vitamins together, and decide when and how to share the news. Begin looking into parental leave policies at work.
