Your developing baby: week 30 onwards

You are now in the last stages of your pregnancy. During this time, your baby will gain weight more quickly than before. You may start to feel uncomfortable as your baby gets bigger.

Find out about your baby’s development and your changing body.

Your developing baby

30–32 weeks

Your baby’s eyes are open and baby can see and hear. Baby doesn’t grow much more but does gain weight. There’s less room for your baby to move around.

33–36 weeks

Baby may have a full head of hair. Your baby usually settles into a head-down position, and moves down so that their head is in your pelvis. Your baby’s lungs are almost fully grown.

37–40 weeks

Baby keeps gaining weight. The downy hair and vernix coating are gone. Your baby may sit low in your pelvis.

By 40 weeks your baby is about 50 cm long and weighs over 3 kg – remember though that all babies are different; babies can be longer or shorter, bigger or smaller. Your baby is now fully developed and the lungs have matured, ready for birth.

41–42 weeks

Most babies are not born on their due dates. You may be waiting a little bit longer for baby to arrive!

Your changing body

Both you and your baby have grown a lot. You may have aches and pains or other problems due to the extra weight that you are carrying around – see the Common complaints in pregnancy page to find out more.
