If you’ve reached 25 weeks with twins, you may be noticing stronger kicks, a rapidly growing baby bump, and symptoms like back pain, heartburn, or shortness of breath. While these changes can feel overwhelming, they’re often a normal part of a twin pregnancy. Because twin pregnancies account for approximately 2-4% of all births worldwide and carry a higher risk of preterm birth and other pregnancy-related complications, they require closer prenatal monitoring than singleton pregnancies (1).

In this article, you’ll learn how your babies are developing at 25 weeks, the common symptoms and body changes to expect, and practical tips to help you stay healthy and comfortable during this stage of your twin pregnancy.

The Growth of the Babies at 25 Weeks

The rate at which your babies were growing in the previous weeks will continue to be at the same pace, if not at a higher one. A lot more changes are expected in the upcoming weeks, which will ensure that your twins or triplets can survive outside the womb, and the growth is focused entirely on making that happen.

The lungs of the babies will develop around this time. The lungs take quite some time to start functioning, but by now, they will increase in size, causing them to fill out as much as possible so that they can take air in a substantial amount. In this week, as the size and the network within the lungs increases, numerous blood vessels develop as well along with a circulatory system (2). They prove to be the crux for keeping the babies alive, allowing the lungs to absorb oxygen from the inhaled air into the blood, which can then be transported to different organs in the body.

The skin that babies have around this stage is still a little translucent. But it will develop a brilliant sheen by itself, as it starts to form a tan and the fat deposits grow over it. Along with it, the blood capillaries begin to spread their branches all over the body. When the blood starts to pump through them, they start to get a reddish-tinge. This is precisely what makes the newborns get a healthy pinkish coloured skin.

What Is the Size of the Babies?

If you’ve ever seen a large turnip in the farms, that’s pretty much the size of your babies in this week. Their length and weight increase week by week, improving along the journey. When measured, their height usually comes somewhere around 35 centimetres while their weight tends to hover close to 650-700 grams. The weight of each baby, in the case of twins or triplets, will be slightly less, and the same goes for their height (3).

These are the foetal developmental milestones you babies have or are meeting at week 25. You will also go through a gamut of changes this week. The rest of the article will address most changes expecting mothers go through at week 25 of their pregnancies.

Common Bodily Changes

The changes that women pregnant with multiples or twins experience in the 25th week of their pregnancy are usually an extended version of their previous symptoms.

1. Lower Sex Drive

A decrease in sex drive is common during this stage of pregnancy. Hormonal changes, a growing belly, and increasing physical discomfort can reduce interest in intimacy (4). These changes are temporary and completely normal, so open communication with your partner can help you both adjust.

2. Stronger Baby Movements

Your babies are becoming more active, making their kicks, stretches, and rolls much easier to feel (5). As the uterus expands and presses against your abdominal wall, some movements may feel strong or even slightly uncomfortable, especially when both babies are active.

3. Increased Fatigue

Carrying twins places extra demands on your body, so it’s natural to feel more tired as pregnancy progresses. Daily activities may become more exhausting, making it important to rest whenever possible and avoid overexertion.

Symptoms of Twin Pregnancy at 25 Weeks

The pressure that comes with a growing pregnancy will start making itself more evident in the coming weeks. This can make the 25 weeks pregnant with twins symptoms more evident. Here are some of them (6):

1. Indigestion and Bloating

As your uterus expands, it puts pressure on your stomach and intestines, slowing digestion. This can lead to indigestion, bloating, excessive gas, and a feeling of fullness even after eating small meals. Eating smaller, more frequent meals may help ease discomfort.

2. Constipation

Hormonal changes and pressure on the intestines can slow bowel movements, making constipation more common. Staying hydrated, eating fibre-rich foods, and engaging in light physical activity can help promote regular bowel movements.

3. Frequent Urination

Your growing uterus places increasing pressure on the bladder, reducing its capacity to hold urine. As a result, you may find yourself making more frequent trips to the bathroom, even if only a small amount of urine is passed each time.

4. Haemorrhoids

The extra pressure from carrying twins, along with constipation, can increase the risk of haemorrhoids. These swollen veins around the rectum may cause pain, itching, or discomfort, especially during bowel movements.

5. Heartburn and Acidity

Pressure from your growing babies can push stomach acid back into the oesophagus, causing heartburn and acid reflux. Avoiding spicy or greasy foods, eating smaller meals, and remaining upright after eating can help reduce symptoms.

25 Weeks Pregnant With Twins Is How Many Months?

If you are pregnant with twins at 25 weeks, you are approximately 6 months and 1 week pregnant and nearing the end of your second trimester.

Twin Pregnancy – Belly at 25 Weeks

Some women have their bellies growing right until they deliver the child, whereas some, after a certain point in the pregnancy, have their stomachs pretty much around the same size until delivery. Both cases are normal and the babies delivered are entirely healthy. At week 25, you could gain more weight, which is shown on your belly eventually. The final trimester is nearly here, and the baby continues to grow and mature.

Twin Pregnancy at 25 Weeks – Ultrasound

The 25th week is usually not a time where doctors would recommend an ultrasound scan, since within a week or two, conducting a fortnightly scan would become the norm to track the final development of your babies. If it is done, you will notice that your babies will indulge in some thumb sucking or swallowing exercises to practice their breastfeeding abilities. Similarly, you will also observe them be cute and chubby in the coming weeks.

Pregnancy Diet at 25 Weeks

Anaemia, in this phase of the pregnancy, is common. Hence, it is essential that you adhere to a diet that is rich in oatmeal, beetroots, pulses, and so on. Intake of protein and amino acids is also necessary, along with numerous fruits and vegetables, all of them in a safe quantity (7).

Pregnancy Care Tips at 25 Weeks

Taking care of your pregnancy in the 25th week requires adherence to some straightforward tips. We have also mentioned some things to avoid at 25 weeks pregnant with twins (8).

Dos

Keep track of your weight on a regular basis to check for any discrepancies.
Undertake a glucose screening test to check for signs of diabetes.
Increase the intake of fibre and keep yourself hydrated to help your body deal with digestion issues, especially constipation.
Have scheduled, balanced, freshly made meals to provide your body with the energy it needs.

Dont’s

Avoid skipping exercises altogether but tone them down to not be as stressful.
Don’t give in to the craving for fried foods or canned products.

What You Need to Shop for at 25 Weeks

Your body is going through some changes, and you might need clothes in a bigger size. If you haven’t bought any, you could go shopping and get some in soft and breathable fabrics like cotton. The baby is once its way; there’s time for his arrival, though. However, if you want to save some time and energy later, you can shop for some essentials such as the ones given below:

Diapers that we well within the expiry date.
Lots and lots of tissues.
Book a cradle for your little one.
Some baby clothes, booties, mittens, etc.
Heaters or coolers if the due date is in an extreme season.
Steriliser.
Breast Pump.

Questions Twin Mother Should Ask Doctor

Every prenatal appointment is an opportunity to better understand how your pregnancy is progressing and ensure both you and your babies remain healthy. Here are some important questions to ask your doctor at this stage.

1. Is my twin pregnancy progressing normally for this stage?

2. Are my babies in the right position, and does their position affect my delivery plan?

3. How often will I need ultrasounds or prenatal check-ups from now on?

4. What symptoms or changes should never be ignored during the coming weeks?

FAQs

1. Is it safe to travel when you are 25 weeks pregnant with twins?

It is recommended not to travel after the 28th week of a twin pregnancy. But do consult your doctor even at the 25th week.

2. What is the survival rate of twins born at 25 weeks?

Babies born at 25 weeks are considered extremely premature and require immediate care in a neonatal intensive care unit (NICU). Recent data from the American Academy of Pediatrics show that approximately 82% of babies born at 25 weeks survive to hospital discharge with modern neonatal care (9). However, for twins born at 25 weeks survival rate can vary depending on factors such as birth weight, whether they received antenatal steroids before birth, the presence of medical complications, and the level of care available at the hospital.

3. Can I still exercise safely?

In most uncomplicated twin pregnancies, light to moderate activities such as walking, prenatal yoga, or swimming are considered safe. Always check with your healthcare provider before starting or continuing an exercise routine.

The 25th week of a twin or multiple pregnancy is the beginning of another period of the journey. Along with more physical, hormonal, and emotional changes that cause anticipation and anxiety even, there will still be numerous happy moments that will present themselves to you in the final trimester and keep you engaged and proud to be the mother of your children.
