At 25 weeks pregnant, a baby is roughly the size of a turnip. Babies are roughly 31.8 cm (12.5 inches) from the top of their head to their heel (crown-heel length) and weigh approximately 778 g (27.4 oz).
You’re nearing the end of your second trimester, and your little one has come a long way. Last week, they reached the age of viability, which is when their chance of survival outside of the womb passed 50%. As each week passes, their chance of surviving a premature birth increases.
Psst: Find out how many months pregnant you are if you’re still a bit unsure.
Your baby at 25 weeks
Your baby now has noticeable human characteristics, like hair, skin, and nails. The baby is also starting to plump up and is adding more layers of fat each day.
Here are the key developments your 25-week fetus is going through:
Nose
At 25 weeks, the part of your baby’s nose that senses smell is starting to function. The baby may even be able to smell scents and odours in the amniotic fluid.
With this new nasal development, babies can also start taking their first practice breaths. However, since there isn’t any air in the womb, they’re only “breathing” amniotic fluid right now.
Lungs
The fetus goes through four stages of lung development. This week, the canalicular stage (second stage), which started in week 16, is now complete. The structures responsible for gas exchange have formed and vascularised.
Hair
The hair on your baby’s head is growing. The lanugo, the soft, thin hair that covers their tiny body, is also now in place. However, it won’t stick around for long. Around the seventh or eighth month of pregnancy, most fetuses will shed their lanugo.
Your body around 25 weeks of pregnancy
As you approach your third trimester, you may notice new symptoms start to pop up. Here are some common changes your body may be experiencing during week 25 of pregnancy.
- Restless Legs Syndrome: If you find yourself with a strong desire to move your legs, you might be experiencing restless legs syndrome (RLS). This feeling is more common in the evening, although it can strike at any time. Although it’s not entirely clear what causes RLS, some experts believe it may result from low iron or folic acid levels.
- Haemorrhoids: More than 50% of pregnant women experience haemorrhoids. They’re a form of varicose veins caused by increased blood flow and the uterus pressing down on the rectum, which causes the veins to swell. Although they’re not dangerous, they can be quite uncomfortable and may cause rectal bleeding. Eating fibre-rich foods and keeping hydrated can help keep haemorrhoids at bay.
- Carpal Tunnel Syndrome: If your hands and wrists start to feel tingly or numb, you’re likely experiencing carpal tunnel syndrome. During pregnancy, your blood volume increases, causing your wrists to swell and put extra pressure on the nerves. To reduce the symptoms of carpal tunnel, take frequent breaks from repetitive tasks that use your hands or look into buying wrist splints.
- Thicker hair: Have you noticed that your hair is looking a little fuller these days? You’re not growing more; you’re just not shedding as much as you normally would, thanks to hormonal changes. Enjoy this fullness while it lasts—most women experience hair loss after giving birth.
- Trouble sleeping: As your bump gets bigger, you may start to experience trouble sleeping at night. There are a few things you can do to help get some decent shut-eye. Try to drink more water earlier on in the day. That way, you won’t be interrupted by as many nighttime bathroom trips. Following a regular exercise routine can also help you enjoy a more sound slumber. Lastly, don’t underestimate the power of a comfortable pregnancy pillow.
Taking care of yourself when pregnant at 25 weeks
Now is as good a time as ever to focus on your health and well-being.
Here are some tips for living your best pregnancy life:
- Keep a journal: Writing your thoughts and feelings on paper can help you understand them better. It’s a great tool for improving your mental health, and it can be a valuable thing to look back on. Journaling can help inspire creativity, relieve stress, and set goals.
- Look into antenatal classes: A great way to prepare for childbirth is to take antenatal classes. Most expectant parents find these classes very beneficial. They provide you with information on labour, birth, and caring for your newborn. Most people take these classes about eight to ten weeks before their baby is due, which is when they are 30 to 32 weeks pregnant. You still have a bit of time before you need to book into anything. But you might find several options in your area, so it’s best to get a head start with looking.
- Focus on dental health: Did you know there’s actually a link between good dental hygiene and carrying a baby to full term? It’s true. Research has found a connection between expecting women and healthy oral practices. Keeping your mouth clean means you’ll reduce the risk of transmitting bacteria through your blood and amniotic fluid to your fetus. These oral infections can trigger premature delivery. Make sure to brush your teeth at least twice a day and floss regularly.
- Stay active: Working out prepares your body for the rigours of childbirth. This means women who regularly exercise are much more likely to have a smoother labour and delivery. It’s totally safe to stay active right until the end of your pregnancy. Just remember to choose pregnancy-safe workouts like walking, swimming, and pre-natal yoga.
