Third Trimester Guide for Dads

The final stretch. Your baby is nearly ready, your partner is uncomfortable, and the clock is ticking. This is where preparation meets reality — here's what to do week by week until delivery day.

Medical Disclaimer: Content is for informational purposes only and does not replace professional medical advice. Always consult your healthcare provider.

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.
