Baby development at week 26
Eyelids may open and close. Inhaling/exhaling motions strengthen. Immune factors continue developing with help from you via the placenta.
Average size estimates for week 26 are about 35.6 cm and 760 g — roughly ear of corn. Your ultrasound report and clinician’s dating override any website average.
What you might feel
Shortness of breath can appear as the uterus lifts the diaphragm. Slow down stairs and pause without apology.
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.
