Week 31


41 cm

Your baby is now heading for a massive growth spurt over the next couple of weeks. Their body is growing and so is their brain capacity. With your growing bump, it might be getting harder to sleep, but make sure you get as much rest as possible.

At roughly 41cm long and 3lb 3oz your baby is rapidly putting on weight. The lanugo, or fine hair, which has covered their body to keep them warm, will begin to disappear as the fat they’ve gained now provides more than enough insulation. Their memory is developing and they’ll be able to recall memories from their time in the womb once they’re born. One study found that babies who were played a particular tune while in the womb responded to it after birth, while those babies who hadn’t heard it before birth exhibited no response.

Your baby may still be quite high up, meaning your uterus is pressing on your diaphragm which can leave you feeling breathless. Your baby may not drop down into your pelvis until around 36 weeks if you’re a first-time mum, and for mums expecting subsequent babies it may not happen until the beginning of labour. In the meantime, try to relax and rest as much as possible.

Although feeling breathless is common at this stage, shortness of breath can also be a sign of anaemia. Anaemia is caused by a deficiency in iron and you’re more likely to develop it during pregnancy. It’s treated simply by adding extra sources of iron to your diet – through food or supplements. If you’re also feeling tired all the time this can be another sign of anaemia, so speak to your doctor.
