What Happens at 22 Weeks Pregnant?

At 22 weeks pregnant, your baby is growing rapidly and experiencing significant developmental milestones. This week marks a crucial period for sensory development, lung maturation, and physical growth. Your little one is now about the size of a papaya and is gaining weight steadily. As you approach the halfway point of your pregnancy, you may notice more pronounced movements and even begin to feel your baby’s unique personality emerging.

Baby’s Size and Growth at Week 22

By week 22, your baby weighs about a pound and is approximately 10.9 inches long from head to toe. Over the next four weeks, your baby will double in size, making this a period of rapid growth. The body is becoming more proportionate, with the head making up less of the total body length as the torso and limbs continue to develop.

Development of the Senses

One of the most exciting aspects of week 22 is the rapid development of your baby’s senses. Each day, your baby’s ability to see, hear, smell, taste, and feel is becoming stronger.

Hearing

Your baby’s hearing is now more developed, and she can recognize your voice. She can also hear sounds from inside your body, such as your heartbeat and stomach gurgling. External sounds, like music or loud noises, may cause your baby to move suddenly. Talking, singing, or reading to your baby can help strengthen this bond and stimulate her auditory development.

Touch

Your baby is busy practicing sucking her thumb and developing a firm grasp. She may reach out and grab the umbilical cord, stick out her tongue, and even lick the cord while holding it. These movements help develop her sense of touch and prepare her for life outside the womb.

Taste and Smell

Although your baby’s nostrils have been plugged to keep amniotic fluid out, they are now opening for practice breathing. Your baby will go through the motions of real breathing but inhale amniotic fluid instead of air. This process helps develop the lungs and the muscles needed for breathing. The taste buds are also developing, and your baby can taste the amniotic fluid, which is influenced by your diet.

Sight

Your baby’s eyelids are still shut, but her eyes are moving behind them. Tear ducts are starting to develop, and eyebrows may begin to appear. Although your baby cannot see yet, the eyes are becoming more sensitive to light.

Lung Development

The lungs are developing rapidly at week 22. They will begin making a protein called surfactant, which allows the lungs to inflate without collapsing and deflate without sticking together. This is a crucial step in preparing your baby for breathing outside the womb. Although the lungs are not yet ready for life outside, this development is essential for future respiratory function.

Physical Development

At 22 weeks, your baby is no longer bald. There is some hair on her head, which is most likely white because the pigment that gives it color hasn’t been made yet. The brain is also developing rapidly, and your baby’s movements are becoming more coordinated.

Vocal Cords

Vocal cords are fully developed at this point, and your baby can really hiccup now. These hiccups may feel like regular, jerky movements and are a sign of healthy development.

Grasp and Movement

Your baby is developing a firm grasp and may reach out and grab the umbilical cord. She can stick out her tongue and may even lick the cord while holding it. These movements help develop her sense of touch and prepare her for life outside the womb.

What to Expect as a Mom

As your baby grows, you may notice more pronounced movements and even begin to feel your baby’s unique personality emerging. You may also experience some common pregnancy symptoms, such as back pain, swelling, and increased appetite.
