What’s happening with the baby at 20 weeks pregnant?

At 20 weeks pregnant, you're officially halfway through your pregnancy, and your baby is growing rapidly! 

Baby's movements

Your baby is now moving around more, and you might begin to feel those movements, especially if it's your first pregnancy. Some women describe it as feeling like little flutters, bubbles, or even popcorn popping. Baby kicks and rolls are becoming stronger and more frequent.

Baby’s development

• Baby hiccups: If you notice rhythmic, jerking movements, it could be baby hiccuping. This is completely normal and something many women start to feel around this time.

• Taste buds: Your baby's taste buds are now developing, and they can detect flavors from the foods you eat, as molecules of your food pass through your bloodstream into the amniotic fluid. While it's not certain that babies can actually "taste," some research suggests that babies may be able to sense the tastes of different foods and develop preferences that could influence their tastes after birth.

• Baby’s skin and hair: Baby’s skin is still thin, but it’s developing rapidly. It’s covered with a protective waxy coating called vernix caseosa, which helps protect the skin from the amniotic fluid. Hair is starting to grow on their scalp, though it may still be very fine.

Baby’s senses

The development of your baby’s sensory systems is also progressing. The brain is forming specialized areas for taste, smell, hearing, vision, and touch, which will help them interact with the world after birth.

You may even notice your baby responding to sound. Your baby can hear sounds from the outside world, like your voice, your heartbeat, and even other noises.

How big is your baby at 20 weeks pregnant?

At 20 weeks pregnant, your baby is about the size of a banana.

• Length: Approximately 25 cm (10 inches) from head to toe.

• Weight: Around 300 grams (10.5 ounces).

Your baby is growing rapidly, and as the second trimester continues, they'll continue to put on weight and get longer, making room inside your uterus.

How is your belly at 20 weeks pregnant?

• Belly size: The uterus has expanded enough that it is now about halfway between your pubic bone and your belly button. You might even start to see a visible bump if you haven't already.

• Changes in shape: You may notice your belly becoming rounder and firmer, as the baby grows and your body adjusts to the changes. Some women may also notice stretch marks appearing, especially around the belly, breasts, or thighs.

• Fundal height: Your doctor or midwife will measure your fundal height (from the pubic bone to the top of the uterus) during this visit to track your baby’s growth. At 20 weeks, the fundal height in centimeters will be roughly the same as the number of weeks of pregnancy.

Common symptoms and how to manage them?

1) Increased appetite

As you reach the halfway mark of your pregnancy, you may notice you're hungrier than usual. Your body is working hard to support both you and your growing baby, so it's important to eat enough nutritious food.

How to manage:

• Opt for healthy snacks such as fruits, vegetables, nuts, and yogurt.

• Try to eat smaller, more frequent meals to prevent overeating and keep your energy steady.

• Drink plenty of water to stay hydrated and curb hunger.

2) Backaches

As your baby grows, your body is shifting to accommodate the increased weight, which can lead to back pain.

How to manage:

• Use a supportive pillow when sleeping.

• Consider wearing a maternity belt for extra support.

• Gentle exercises like prenatal yoga or swimming can help strengthen your back muscles.

• Take breaks and change positions frequently if you're sitting for long periods.

3) Leg cramps

Leg cramps, especially at night, are common during pregnancy, likely due to changes in circulation and your growing uterus putting pressure on certain nerves.

How to manage:

• Stretch your legs before bed.

• Stay hydrated and avoid standing or sitting in one position for too long.

• Gently massage the area if you get a cramp, and flex your foot to relieve it.

4) Skin changes

You might notice changes in your skin, such as a darkening of the skin on your face (known as the "mask of pregnancy"), a dark line running down your belly (linea nigra), or stretch marks.

How to manage:

• Use sunscreen to prevent worsening of skin pigmentation.

• Keep your skin moisturized to reduce the appearance of stretch marks.

• These skin changes are often temporary and fade after pregnancy.

5) Swelling

Swelling, especially in your feet, ankles, and hands, can occur due to increased blood volume and pressure from the growing uterus.

How to manage:

• Elevate your feet when sitting.

• Wear comfortable shoes and avoid standing for long periods.

• Drink plenty of fluids to help reduce swelling.

6) Heartburn

The growing uterus can put pressure on your stomach, leading to heartburn or acid reflux.

How to manage:

• Eat smaller meals throughout the day.

• Avoid spicy, fatty, or acidic foods that may trigger heartburn.

• Sleep with your upper body elevated, and consider talking to your healthcare provider about safe heartburn medications if needed.

Frequently asked questions at 20 weeks pregnant

What is the "fundal height" and why is it important?

Fundal height refers to the measurement from your pubic bone to the top of your uterus. It gives your healthcare provider an indication of your baby's growth. Starting around 24 weeks, the height in centimeters usually matches the number of weeks pregnant you are, giving a helpful marker for fetal development.

Why am I feeling more tired than usual?

Fatigue is common during the second trimester as your body adjusts to the demands of pregnancy. Your growing uterus puts pressure on your body, and you may be experiencing changes in your blood flow and energy levels.

Is it normal to feel baby movements at 20 weeks?

Yes, many women begin to feel their baby move between 16-22 weeks. These first movements may feel like flutters, bubbles, or gentle taps. If you haven't felt movement yet, don’t worry—every pregnancy is different.

What is the best way to manage my growing appetite?

It’s important to eat healthy, balanced meals and snacks to meet your increased calorie needs. Focus on nutrient-dense foods like fruits, vegetables, lean proteins, and whole grains. Eating small, frequent meals can help keep hunger at bay and maintain your energy levels.

Can I continue exercising at 20 weeks pregnant?

Yes, most women can continue exercising during pregnancy, but it's important to choose safe activities like walking, swimming, or prenatal yoga. Always check with your healthcare provider before starting or continuing any exercise routine.

Should I be concerned about my belly growth?

Your belly will continue to grow as your baby develops, and you may notice that your bump becomes more pronounced by 20 weeks. If you're concerned about the size of your belly, or if you notice any unusual symptoms, talk to your healthcare provider.

What is "baby hiccups" and is it normal?

Baby hiccups feel like rhythmic jerking movements inside your belly. They are a normal part of fetal development and can start around 20 weeks. It's just your baby's diaphragm practicing for breathing outside the womb.

How can I prepare for my mid-pregnancy ultrasound?

At 20 weeks, your mid-pregnancy ultrasound will check your baby's growth, anatomy, and organs. You may want to drink water before the scan to fill your bladder, as it can make it easier for the technician to get a clear image.
