Baby development at week 34
Central nervous system refinements continue. Vernix may thicken then lessen. Baby’s rhythms can strongly affect your night waking.
Average size estimates for week 34 are about 45.0 cm and 2146 g — roughly pineapple. Your ultrasound report and clinician’s dating override any website average.
What you might feel
Braxton Hicks can be convincing. Time them if they become regular, closer, or painful — and call when your clinician advised you to.
You are in the third trimester. Two pregnancies at the same week can feel completely different — treat these notes as orientation, not a checklist you must match.
Movements in week 34
By now, many clinicians encourage intentional awareness of fetal movement. Learn your baby’s usual active window, then use Preglo’s kick counter to log a calm session. Read how to count baby kicks if you want a simple method, or the 10-kick count overview. If movements feel clearly reduced, contact your care provider — see reduced fetal movement.
What to track this week
- Symptoms, mood, sleep, and energy in your daily log
- Water intake toward a simple daily goal
- Appointment dates and questions for your care provider
- Scan dates and follow-up notes after ultrasound visits
- Kick sessions once movements feel regular — same time of day when you can
- Tightenings or early labor patterns with the contraction timer if needed
