How your baby is growing this week

Watermelon size — 20 inches, 7-7.5 lbs. Fully cooked. Brain and lungs are the last organs to mature, and they are done. Baby is adding 0.5 oz of fat per day. Ready for launch at any moment.

What your partner is going through

Discomfort is maxed out. She cannot sleep, sit, stand, or lie down comfortably. Cervix checks are weekly and unpleasant. Mentally, she is cycling between "get this baby out" and "I am not ready." Both are valid.

What to focus on this week, dad

  • 01Boundary Ops: block the "is baby here yet?" texts proactively. Send a group message: "We will announce when baby arrives. No need to check in. We love you and will share the news ASAP"
  • 02Final sweep: car seat installed and inspected, hospital bags in car, house clean, pets arranged, work handed off, freezer stocked, phone charged. Run the checklist one more time

Connect with your partner

Tell her you trust her body and her strength. She is terrified of labor whether she shows it or not. Your calm confidence — even if you are faking it — is the most valuable thing you bring to the delivery room.
