Second Trimester Guide for Dads

The “golden trimester.” Morning sickness fades, energy returns, and the pregnancy starts to feel real. This is when most dads shift from processing the news to actually preparing for the baby.

What to know about the second trimester

What happens this trimester

Your baby grows from about 3 inches to 14 inches. You can find out the sex, see detailed anatomy on ultrasound, and your partner will start showing. Around week 18-22, you may feel the first kicks through her belly.

Dad's role

This is the action trimester. Start the nursery, attend the anatomy scan (week 20), sign up for a childbirth class, and begin researching car seats and cribs. Your partner has more energy now — use this window to knock out big projects together.

Things to prepare

Create a baby registry, finalize your budget for gear and medical costs, start interviewing pediatricians, and look into childcare options if needed. Tour the hospital or birth center. These tasks only get harder in the third trimester.

Key appointments

Anatomy scan (weeks 18-22) is the big one — you will see your baby in detail. Regular prenatal visits continue monthly. Glucose screening typically happens around week 24-28. Be at every appointment you can.
