Development highlights

  • Baby is shedding lanugo and most of the vernix coating
  • All organ systems are mature - Ready for the outside world
  • Weight gain slows as space in the womb runs out
  • Skull plates are still soft and overlapping - Designed by nature for the birth canal

Third Trimester: Birth Preparation Guide

Weeks 28–40 are the final sprint. Baby is gaining weight rapidly, your body is preparing for labour, and the countdown is real. This is the time to finalise your hospital choice, pack your bag, choose your paediatrician, and learn the signs of labour. Antenatal visits increase to every 2 weeks, then weekly from week 36.

Frequently Asked Questions - Week 36

Real labour contractions follow a regular pattern: they come at consistent intervals, last 45–60 seconds each, and get progressively stronger, longer, and closer together over time. Braxton Hicks, by contrast, are irregular, don't intensify, and often ease when you change position or rest. Other labour signs include the 'bloody show' (blood-tinged mucus plug), your waters breaking, or persistent lower back pain that worsens in waves.

Follow the 5-1-1 rule: go to hospital when contractions are 5 minutes apart, lasting 1 minute each, for at least 1 hour. Go immediately if: your waters break (regardless of contractions), you have heavy vaginal bleeding, your baby's movements reduce significantly, or you develop a severe headache, vision changes, or upper abdominal pain. In Singapore, call your hospital's labour ward 24-hour line - They'll advise you.
