30 weeks pregnant - all you need to know

You’re three-quarters of the way there! Your baby is about the size of a large cabbage.

What does my baby look like in week 30? 

The white, greasy substance on your baby’s skin, called ‘vernix’, and their fine fur, or ‘lanugo’, starts to disappear from now.

Your baby’s little lungs are developing nicely - though they may still need some help with their breathing if born before 36 weeks.

Their kidneys are fully functioning and their wee is mixing with the amniotic fluid, which is steadily increasing.

Your pregnancy symptoms in week 30

There are some symptoms to look out for during pregnancy as they may be an indication of a more serious problem.

Find the list of the most important symptoms to look out for here.

Are you having strange dreams about giving birth?

You may be feeling anxious about labour - lots of women start to have vivid dreams about giving birth.

Going to antenatal classes will help you prepare for what happens during labour and will hopefully reassure you.

“I did NCT antenatal classes and that was amazing. We all had the same anxieties and it was good to chat with people going through the same thing.”

If you are very worried about the birth, talk to your midwife. You may also want to complete our pregnancy and post-birth wellbeing plan to help you think about how you are feeling and prepare for after the birth.

Here are some tips to help you stay stress-free in pregnancy.

Is your body getting ready for labour?

Towards the end of your pregnancy, but before you go into labour, you may see signs that your baby will be arriving soon.

Find out about 4 ways your body gets ready for labour.

What to do in week 30

Did you know that women who do stay active during their pregnancy (walking, dancing, swimming and so on) can have a shorter labour time, a better delivery and less risk of complications at birth? If you are having an uncomplicated pregnancy you can stay active right up until the birth of the baby. Read more about staying active in pregnancy here.

Preparing for your newborn

Make a list of what you need for your newborn baby. This will include clothes, somewhere for your baby to sleep, a pram and/or car seat, and other essentials.

There’s no need to buy it all at once. Most things apart from the basics can wait until you and your baby are home.

What’s the best position for me to lie in?

Research shows that lying on your side is particularly good for your baby, improving circulation to the placenta so he or she gets more nutrients. Read more about the safest position to lie in during pregnancy.

From the third trimester, it can also encourage your baby into a good position for the birth.

If you’re not sleeping very well, these tips could help.

What is a caesarean section?

A caesarean section is an operation where an obstetrician makes a cut in your bikini line and womb and lifts your baby out through it.

It can be planned (also known as elective) due to health complications or the position of the baby.

It can also be decided during labour – known as an emergency caesarean (although this doesn’t necessarily mean your baby is in danger, it just means the caesarean hasn’t been planned).

    3d scans can enhance things a lot more than the normal obstetric scans so please do not worry unnecessarily. 3d scans are very detailed so anything unusual should have been identified, but ask your daughter to chat to her midwife if she is concerned

    My daughter had a 3D scan at 28 weeks approx. The babies hand looks .... Odd, like it had nodules, ie rheumatism and one finger seemed long, do scans distort the babies features. Maybe I'm just neurotic, I hope so, the lesser of two evils!!
