At 26 weeks, your baby is about the size of a zucchini—roughly 14 inches long and weighing about 1.7 pounds. A major milestone this week: your baby’s eyes are opening for the first time! Your baby can now see light through your abdomen and will turn toward bright lights. You’re in the final stretch of the second trimester, and the third trimester is just around the corner.
Baby Development at 26 Weeks
Your baby measures about 14 inches and weighs approximately 1.7 pounds. The most exciting development: your baby’s eyes are opening for the first time. The eyelids, which have been fused shut since early pregnancy, are now separating, allowing your baby to see—though vision is still blurry.
Your baby’s lungs continue producing surfactant. The immune system is maturing, with antibodies transferring from you through the placenta. Brain wave patterns show that your baby now has distinct sleep-wake cycles. Hearing is well-developed—your baby recognizes your voice and may respond to music.
Your Body This Week
Your uterus extends about 2.5 inches above your belly button. Weight gain is typically 16-22 pounds. You may notice your baby hiccupping—a rhythmic, gentle pulsing in your abdomen. Braxton Hicks contractions may be more frequent.
Sleep is becoming more challenging. Your growing belly, frequent urination, and back pain can disrupt rest. Our sleep guide offers strategies for better rest.
Common Symptoms at 26 Weeks
Baby hiccups: Regular, rhythmic movements that feel different from kicks. They’re normal and a sign of diaphragm development.
Pelvic girdle pain: The hormone relaxin loosens pelvic joints, causing discomfort. A maternity support belt can help.
Headaches: Hormonal changes, dehydration, and fatigue trigger headaches. Stay hydrated and rest.
Insomnia: Between bathroom visits, discomfort, and anxiety, sleep quality may decline. Establish a calming bedtime routine.
What to Do This Week
Discuss your birth plan with your provider. Our birth plan template helps organize your preferences.
Tour your delivery hospital or birth center if you haven’t already.
Continue exercising with pregnancy-safe activities.
Prepare for the third trimester—arrange any needed time off work, discuss parental leave, and finalize childcare plans.
Nutrition Spotlight: Iron-Rich Foods
Iron needs increase as your blood volume peaks. You need 27 mg daily. Pair iron-rich foods (lean meat, beans, spinach) with vitamin C for better absorption. If you’re anemic, your provider may recommend iron supplements. Visit our nutrition guide.
