    Baby's development at 27 weeks pregnant

    At 27 weeks your baby is developing nicely. All curled up, the size of your baby at 27 weeks is about the size of a cabbage.

    There’s still plenty of growing to do though – and your baby’s lungs are one of the last things to develop. Baby has all the right parts to start breathing but their air sacs have more growing to do and they’re yet to produce something called ‘surfactant’. This substance keeps the airways open and makes it possible for baby’s lungs to breathe in air after delivery. It’ll be week 35 or so before they have enough to breathe properly.

    Baby’s heart at this stage is fully developed and going strong. Something to look forward to hearing again at your next check-up.

    Nutrition at 27 weeks pregnant

    If you’ve avoided heartburn so far, don’t relax too soon, it can still bite you on the tum as you get near the end. In fact, *20-70% of women suffer from heartburn, indigestion or reflux during pregnancy, especially in the second and third trimesters where symptoms tend to get worse. That’s because baby is getting heavier and their weight is pushing on your stomach and intestines. This pressure can cause stomach acids to be squeezed into your oesophagus, relaxing the muscle at the top, creating that uncomfortable burning sensation.

    If heartburn is interrupting your sleep, add an extra pillow so you’re sleeping almost upright. Our resident dietitian Ellie advises eating light meals in the evening so you’re not going to bed on a full stomach. If you get hungry later on, yoghurt or a piece of non-acidic fruit like a banana should tide you over until breakfast time. You may want to consider cutting out acidic, spicy or fatty foods, as these can make things worse. Speak to your GP if changing your diet doesn’t help.

    Getting ready for labour and beyond

    Antenatal classes are helpful, even for experienced mums. That’s because researchers are constantly discovering new things that can help your pregnancy, and delivery methods change a lot too.

    For instance, breathing exercises have always been part of antenatal classes, but now hypnobirthing is covered as well. This adds relaxation, visualisation and mindfulness methods to the traditional breathing techniques, helping you concentrate on your body and the birth of your baby.

    Antenatal classes will also help you understand what’s happening inside your body during labour and delivery. It’s a good chance to find out about pain relief and give you hospital options too.

    For more information about antenatal classes, speak to your midwife.
