Week 26 Pregnancy

Second Trimester

You are 26 weeks pregnant and in your second trimester. Your baby is about the size of a spring onion. This week's key development: Eyes Opening. NHS note: Routine midwife check.

Baby's Development

Your baby is about the size of a spring onion.

Eyes Opening — Your baby's eyelids, which have been fused shut, are beginning to open. Their eyes are now sensitive to light, and they may respond to a bright light shone on your belly. Brain wave activity for both hearing and sight is now detectable.

Practical Advice for Week 26

Nutrition

  • Continue vitamin D daily.
  • Vitamin A is important but avoid liver products which contain dangerously high levels.
  • Eat plenty of colourful fruits and vegetables for antioxidants.
  • Include oily fish for DHA — essential for your baby's developing eyesight.

Exercise

  • Consider prenatal yoga or aqua natal classes — both are excellent in the third trimester lead-up.
  • Practise good posture — your spine is under increasing pressure.
  • Avoid lying flat on your back — use an incline or lie on your side.
  • Pelvic tilts and cat-cow stretches ease back tension.

Wellbeing

  • Your baby's eyes are opening — they can now see light through your belly.
  • Insomnia may worsen — establish a calming bedtime routine.
  • Back pain is common — a warm (not hot) wheat bag can help.
  • Start thinking about your birth environment — what makes you feel safe and calm.

Preparation

  • Start writing your birth plan — your midwife can help you refine it.
  • What kind of pain relief interests you? Gas and air, water birth, epidural, or hypnobirthing?
  • If you want a home birth, discuss it with your midwife — it's an option for low-risk pregnancies.
  • Ensure your car seat is compatible with your car.

Tip of the Week
