Week 26

Week Twenty-Six

Week 26

  • Your baby may weigh about two pounds now (average is 1.7 pound, 760gm) and is 14 inches (35.6cm) in length

  • To support the fetus’s growing body, the spine is getting stronger and more supple. Though no longer than the span of the average adult hand, it is now made up of 150 joints, 33 rings, and some 1,000 ligaments.

  • Air sacs in the lungs form now.

  • Lungs begin to secrete a greasy substance called surfactant. Without surfactant the fetal lungs would stick together and couldn’t expand after the baby is born.

  • Although they’ve been sealed shut for the last few months, your baby’s eyes are opening and beginning to blink this week. Depending on ethnicity, some babies will be born with blue or gray-blue eyes (which may change color in the first 6 months of life) and some will be born with brown or dark eyes.

  • Retinas begin to form.

  • Brain wave activity for hearing and sight begins to be detectable.

  • Fetal brain scans show response to touch. If you shine a light on your abdomen, your baby will turn his head, which according to researchers, means her optic nerve is working.
