Baby development at week 25
Hands find face and cord. Capillaries form under skin, adding color. Sleep and active periods become more rhythmic.
Average size estimates for week 25 are about 34.6 cm and 660 g — roughly ear of corn. Your ultrasound report and clinician’s dating override any website average.
What you might feel
Braxton Hicks may be more noticeable. Practice slow breathing when a tightening comes and goes.
You are in the second trimester. Two pregnancies at the same week can feel completely different — treat these notes as orientation, not a checklist you must match.
Noticing movement in week 25
Flutters often become clearer around mid-pregnancy, though timing varies widely. You do not need a formal count yet for every pregnancy — casual awareness is enough. When patterns feel regular later, Preglo’s kick counter is ready without a separate app.
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
A calm next step in Preglo
