How your baby is growing this week

Eggplant size — 14.8 inches, 2.5 lbs. Brain developing deep grooves and folds for more surface area. Survival odds if born now are over 9 in 10 (92-94%). REM sleep cycles active — baby is dreaming. Movements are strong and regular now, which is why daily kick counts start this week.

What your partner is going through

Welcome to the third trimester. Fatigue returns hard — she is carrying 15-25 extra pounds. Sciatica (shooting pain down the leg) as baby presses on nerves. OB visits move to every 2 weeks; if she is Rh-negative, the RhoGAM shot happens around this appointment.

What to focus on this week, dad

  • 01Kick counts start now — this is your monitoring job for the rest of the pregnancy. Once a day, count baby's movements: 10 kicks, rolls, or jabs within 2 hours is the benchmark (usually much faster). Noticeably fewer than her normal, or a sudden drop, means call the OB the SAME day. Do not wait until morning.
  • 02Tdap: if you've never had one, or it's been 10+ years, get it now — the CDC wants caregivers vaccinated at least two weeks before meeting the baby, and babies can come early. Whooping cough kills newborns, and they can't be vaccinated until 2 months

Take over all floor-level household chores — vacuuming, mopping, picking things up off the floor. She cannot bend over comfortably. Do not wait to be asked.
