Your baby at 25 weeks pregnant: Week-by-week guide to development

Welcome to week 25 of your pregnancy! This week, your baby is as big as a head of cauliflower. Here’s what else you can expect this week.

Your Baby

At 25 weeks, your baby is approximately the size of a head of cauliflower, weighing around 660 grams. Their little body is developing even more baby fat, making them look plumper and less wrinkled. Your baby’s skin, once transparent, keeps getting more opaque. Their sense of hearing is advancing, and they can now recognise your voice and other sounds from the outside world. Chat to them, they might respond with a little kick.


Your bump is more pronounced — your womb is now about the size of a football — but you are still feeling energetic. The stretching of your skin as it grows, or rashes that are common in pregnancy, can cause intense itching. Always mention itching to your carer, however, as it can be caused by a serious condition known as obstetric cholestasis. Those red spidery veins appearing on your ankles, legs, or face should vanish after the birth.

Anything else?

As you approach the third trimester, childbirth classes become an important consideration if you haven’t signed up already. These classes can provide valuable insights into labour, delivery, and early baby care. Maintain your exercise routine, whether it’s prenatal yoga, swimming, or leisurely walks – it’s a great way to stay mobile and manage stress. It might be the last thing you want to do, but it’s very likely to help.
