You and your baby are both preparing for the birth process. It's time for childbirth classes to begin.
Week 29
Baby's length from crown to rump: 26cm.
Buy breast pads or shells to avoid embarrassing leaks, as you may be leaking colostrum. This sticky, watery liquid comes before your supply of milk until two days after the delivery.
Your baby stimulates this milk production by secreting hormone-like substances from its adrenal glands.
Week 30 Baby's length from crown to rump: 27cm.
It will take time for you to move about now, and you could find yourself getting quite clumsy. Check your posture whether you're standing or sitting. Always roll on to your side before getting up from lying down as your abdominal muscles will have grown quite loose.
Baby is now piling on the pounds and mimicking breathing movements in preparation for air.
Week 31 Baby's length from crown to rump: 28cm.
Your blood pressure will be monitored closely from now onwards for signs of pre-eclampsia. Backache is almost inevitable now as the ligaments and muscles in the small of your back are relaxing in preparation for labour and birth. You might get varicose veins around this time, too.
If your baby is born from this week onwards, its chances of survival have significantly improved because its lungs have matured. The space in your uterus is very restricted, and your baby's limbs are in close contact with each other most of the time.
Week 32 Baby's length from crown to rump: 29cm.
Start childbirth classes this week if you aren't already going. Your baby is probably head-down by now, and its legs are sticking up into your ribs, which can be quite an unpleasant sensation. Sitting up straight at all times makes this less likely to happen. You might start losing your libido. If you do, talk frankly about it to your partner to prevent it from becoming an issue.
By now, your baby will be very familiar with your voice, and its father's if he's been speaking regularly to your bump.
