What to know about the third trimester
What happens this trimester
Your baby goes from about 2.5 pounds to a full-term 6-9 pounds. Lungs mature, fat layers build up, the brain develops rapidly, and your baby drops into position for birth. Every week counts for development.
Dad's role
You are the logistics officer now. Finalize the birth plan, pack the hospital bags, install the car seat, and know the fastest route to the hospital at any hour. Be the calm, prepared presence your partner needs as delivery approaches.
Things to prepare
Hospital bag for both of you, car seat installed and inspected, nursery complete, freezer meals prepped, pediatrician chosen, and a postpartum plan in place. Handle the house so your partner can focus on her body.
Key appointments
Prenatal visits shift to every 2 weeks, then weekly after week 36. Group B strep test around week 36. Non-stress tests if needed. Know the signs of labor versus false alarms — and when to call the provider.
