Week 36: Your Baby Weighs About 2.6kg
You may experience 'lightening' - the baby drops lower into the pelvis. This can relieve pressure on your diaphragm and make breathing easier, but increases pressure on your bladder and pelvis. 'Lightning crotch' (sharp, shooting pains in the pelvis) is common and harmless.

Baby Development
The baby is shedding most of the lanugo and vernix that covered their skin. The baby is likely in the head-down position with their head engaged in the pelvis. The digestive system is fully developed but hasn't been activated yet as the baby gets all nutrition through the umbilical cord. The baby is practising breathing, blinking, gripping, and sucking in preparation for life outside the womb.
Week 36 Highlight: Your baby is shedding the lanugo and vernix, and their skin is becoming smooth and soft in preparation for birth!

South Africa Specific Info
Your GBS (Group B Streptococcus) swab is typically done this week in the private sector. This is a vaginal and rectal swab to check for bacteria that can be passed to the baby during birth. If positive, you will receive IV antibiotics during labour. In the public sector, risk-based management is more common. Your antenatal visits are now weekly.
