Week 26: Your Baby is the Size of a Courgette

Your uterus is now about 6cm above your belly button. You may notice your blood pressure being monitored more closely at antenatal visits. Sleep disturbances are common - between the baby's movements, frequent bathroom trips, and difficulty finding a comfortable position.

Baby Development

The baby's eyes are beginning to open and can detect light and dark. The brain wave patterns show response to touch, and the nervous system is developing rapidly. The lungs are producing more surfactant. The immune system is absorbing antibodies from you, building up protection for life after birth. The baby can now inhale and exhale amniotic fluid as practice for breathing.

Week 26 Highlight: Your baby's eyes are opening for the first time! They can see light filtering through your belly.

South Africa Specific Info

The glucose tolerance test (GTT) is typically done between 26-28 weeks. In South Africa's public sector, the standard test involves fasting overnight, then drinking a 75g glucose solution. Blood is drawn at fasting, 1 hour, and 2 hours. If diagnosed with gestational diabetes, you will be referred to a dietitian and may need additional monitoring.
