If you've been researching viability statistics, you're not alone — it's one of the most-asked questions in the second trimester. Understanding the numbers helps, but the most important thing to know is this: each week from here adds meaningfully to your baby's development, and the goal remains reaching 39+ weeks. Round ligament pain, shortness of breath, and occasional Braxton Hicks are all expected now — your uterus has expanded significantly this month.
Research childcare options if you plan to return to work — waitlists in many areas are 6–12 months long.
What's happening in your baby's brain this week is more complex than most pregnancy guides acknowledge.
By week 26, EEG recordings show distinct brain wave patterns in the fetus — evidence of the earliest forms of consciousness and sensory processing.
Vision changes in pregnancy are common and usually temporary. Sudden significant changes in vision, however, warrant immediate medical attention as they can signal preeclampsia.
At 26 weeks, the baby has crossed an important threshold: survival outside the womb is now possible with NICU support. Understanding viability at different gestations gives context without anxiety.
Survival rates by gestational age:
These are population statistics, not individual predictions. Each baby and pregnancy is different. What matters most: reaching this point in a healthy pregnancy, not what these numbers might mean for you specifically.
Baby's senses at 26 weeks: The eyes are beginning to open. The retina has developed enough for light perception, and the baby can react to bright light placed against the abdomen. Hearing is well-established — familiar voices are already being learned.
Third trimester begins next week — appointment frequency increases. Confirm your schedule with your provider.
What should you do right now?

At 26 weeks, your baby is approximately 14 inches (35.6 cm) long and weighs about 1.7 lbs (760 g) — roughly the size of a scallion or head of lettuce. Baby is gaining approximately 6 oz per week at this stage.
Common symptoms at 26 weeks: round ligament pain (sharp twinges in the lower abdomen), shortness of breath as the uterus presses on the diaphragm, Braxton Hicks practice contractions, backache, swollen feet and ankles by evening, and vivid dreams.
26 weeks is in the second trimester (weeks 14–27). You have approximately 14 weeks until your due date. Week 27 marks the final week of the second trimester; week 28 begins the third.
The glucose tolerance test (GTT) for gestational diabetes screening is typically scheduled between weeks 24–28. If you're at 26 weeks and haven't had it yet, contact your provider to schedule it. The 1-hour glucose challenge test doesn't require fasting; if elevated, a 3-hour fasting test follows.
Yes — by 26 weeks, fetal movement should be well-established and regular. Most providers recommend starting kick counts now: 10 movements in 2 hours is reassuring. Movement is often strongest after meals and in the evenings. If you notice a significant decrease in movement compared to your baby's normal pattern, contact your provider.
