Baby development at week 28
Eyesight senses light more clearly. Lung air sacs multiply. Baby may settle into more predictable active windows.
Average size estimates for week 28 are about 37.6 cm and 1005 g — roughly cauliflower. Your ultrasound report and clinician’s dating override any website average.
What you might feel
Insomnia, reflux, and pelvic pressure become more common. Side sleeping with pillow support helps many.
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 28
