Baby's development at 27 weeks
Your little one isn’t so little anymore! Baby still has some growing to do, but should now be big enough to lie on your forearm, between your hand and your elbow.
The respiratory system has all the parts it needs to start breathing, but it’s not ready just yet. The air sacs need to develop a bit more, and there won’t be enough surfactant (a substance that helps air move into the cells of the lungs to aid breathing) until week 35. So relax while your baby grows a little more.
Have you been trying to picture how big your little one is? Baby should be about 34 cm long now, so just a bit bigger than a ruler, with the head about the size of a small orange.
We bet your baby is looking just lovely!
Heartburn can occur because baby’s 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.
Having a hard time sleeping? Don’t worry; you’re not alone. Unfortunately, it’s quite normal at this stage of your pregnancy. But there are a few things you can try to help.
If reflux and heartburn is interrupting your sleep, add an extra pillow so you’re sleeping almost upright. Alternatively, have a light evening meal so you’re not going to bed on a full stomach. If you get hungry later on, try some yoghurt and a piece of non-acidic fruit or a slice of whole grain bread with jam. Speak to your GP if changing your diet doesn’t help.
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.
They’ll help you understand what’s happening inside your body during labour and delivery, inform you about pain relief and hospital options, as well as teaching you some good relaxation techniques for when the time comes.
For more information about antenatal classes, speak to your midwife.
