Week 26 opens eyes: the lids that fused months ago unseal, and the baby begins blinking. Brain-wave activity for sight and sound kicks in, making this a big sensory milestone week.
The lungs are working on surfactant production and the air sacs begin to branch. The baby responds more consistently to your voice and touch through the belly. Responding to sound includes calming to familiar songs.
Gestationally, week 26 means you are 25 weeks and 0 to 6 days pregnant, day 176 to day 182 counted from the first day of your last period. This is week 13 of the second trimester (weeks 14–27). Prenatal appointments run about every four weeks in this stretch. Week 28 brings the third trimester and the start of daily kick counts. Across this trimester the baby more than triples in weight, so expect your bump, your appetite, and eventually your waddle to keep pace with the calendar. Every number on this page is an average across pregnancies; your own scan dates and your baby's measurements are what actually describe your week 26.
Do the glucose test this month if you haven't. A humidifier and saline spray help pregnancy nose.
Weeks of pregnancy don't map cleanly to calendar months, but the common division puts week 26 falls in month 2 of pregnancy (weeks 5–8). Week 26 is part of the second trimester, which runs from week 14 to week 27. Gestationally, week 26 means you are 25 weeks and 0 to 6 days pregnant.
At week 26 the baby averages 14.0 in long and weighs about 1.68 lb, roughly the size of a zucchini. Sizes come from fetal growth charts (crown-to-heel length from week 20), and normal variation week to week is wide; your ultrasound measurements always outrank a chart.
