19th Week of Pregnancy: What is this 'Vernix Caseosa' that protects the baby's skin?

Hello! Here we are, another important week in your beautiful pregnancy journey. You are now in week 19. By now, your belly has moved a little forward, and you may have felt the baby growing inside you. You may not even know if you have started to feel the baby's movements yet. Isn't it an exciting time? Let's see what amazing things are happening to you and your little one in your womb during this 19th week.

Baby's amazing development: What happens in week 19?

By this week, your baby is about the size of a small mango! Just imagine... big enough to hold in your hand. The baby is about 15 centimeters long and weighs about 240 grams. Not all babies are the same, so there may be slight variations, right?

What is this white, cheesy thing? – Let's learn about 'Vernix Caseosa'!

Have you heard of this thing called `(Vernix Caseosa)`? Maybe the doctor has told you. This is the most special thing that happens to your baby's body this week. Simply put, this is a white, waxy substance that covers your baby's skin. It looks like cheese. Some people also call it "cheese coating."

This `(Vernix Caseosa)` provides a very important protection to the baby's skin. It's like applying `(Lotion)` to our skin.

Why is 'Vernix Caseosa' so important?

Imagine, the baby is in a bag full of water (`(Amniotic Fluid)`). Just like our fingers shrink when we bathe and stay in the water for too long, what happens if the baby's delicate skin is constantly exposed to that water? The skin can become dry, rough, and flaky.

• Skin protection: That's what this `(Vernix Caseosa)` coating helps to protect. It acts like a protective wall between the baby's skin and the water the baby is in. So the baby's skin doesn't dry out, get scratched, or get chapped.
• Ease during birth: This cover allows the baby to slide a little when it is born, that is, during ``Delivery''.
• Protection after birth: This `(Vernix)` may remain on the baby's skin for a few days after birth. It protects the baby's skin from fungal infections (`(Fungal Infections)`), bacterial infections (`(Bacterial Infections)`). It also helps to control the baby's body temperature.

How is this for premature babies?

Usually, premature babies (`(Premature Babies)`) often have this `(Vernix Caseosa)` covering on their bodies. This is because they are born before it has completely dissolved while they are in the womb. Don't be alarmed when you see it, okay? It's very natural. It will go away on its own in a few days.

Other surprising changes in the baby

Not only is there '(Vernix Caseosa)', but many other things about the baby are developing this week.

• Fine hair (Lanugo):A baby's body develops very fine, thin hairs. This is called `(Lanugo)`. This `(Lanugo)` also helps the `(Vernix Caseosa)` to stick to it. As the baby gets closer to birth, most of this `(Lanugo)` will fall off.
• Do you feel those little movements?: By now, your baby is moving quite a bit. If you haven't felt it yet, you will start to feel it in about a week or two. At first, it feels like butterflies fluttering in your stomach, or like bubbles popping. This is called ``Quickening''.
• Can you hear your mother's voice?: Your baby's ears are now very developed. Your baby is now starting to hear the sound of you talking, your heartbeat, and even sounds outside. So this is the best time to talk to your baby and sing songs.
• Taste buds are also starting to form on your baby's tongue. The taste of what you eat can also be passed on to your baby through the amniotic fluid!
• Little Kidneys Working: The baby's kidneys (`(Kidneys)`) are now starting to make urine. That urine is then mixed back into the `(Amniotic Fluid)`. Don't worry, this is a very natural process.
• Genitals: An ultrasound scan this week may even reveal the baby's genitals. This means you can also find out if it's a girl or a boy.

How is mom doing this week?

Not only the baby, but your body is also going through big changes this week.

• Belly is getting bigger: You may notice your belly is now moving forward. The uterus (`(Uterus)`) is now right up to the navel (`(Navel)`).
• Some new difficulties:
• Backache: As your belly grows, the weight on your back increases, which can lead to backache. Keep a small pillow under your back when sitting in a chair. Keep a pillow between your legs when sleeping.
• Round Ligament Pain: As the uterus grows, the ligaments that hold it together stretch, so you may feel a sharp pain in your thighs or lower abdomen when you stand up suddenly, laugh, or cough. It will subside after a while.
• Dizziness: Sometimes you may feel dizzy because your blood pressure may drop slightly. Get up slowly, without getting up suddenly.
• Leg swelling and pain (`(Leg Cramps)`): Some people may experience swelling in their legs and pain at night, as if they are rolling over. Drink plenty of water throughout the day. Eat foods high in potassium (`(Potassium)`) (bananas, avocados).
• Heartburn, constipation: These are common during pregnancy. Eat small meals rather than large meals. Eat more fiber-rich foods, fruits, and vegetables.
• Skin changes:A dark line (`(Linea Nigra)`) may appear down the middle of the abdomen. Spots (`(Chloasma/Mask of Pregnancy)`) may appear on the face. These are caused by hormonal changes and will subside after the baby is born.

This week's important 'Anomaly Scan' test

A special ultrasound scan is often performed between 18 and 22 weeks. This is called an Anomaly Scan (sometimes called a Detailed Scan). This scans the baby's organs (heart, brain, kidneys, limbs) in great detail to see if they are developing properly. It also checks the position of the placenta and the amount of amniotic fluid. This is a very important test, so be sure to have it done on the day your doctor tells you.

Things you can do this week for your well-being

You need to take good care of yourself during this time.

• Nutritious food: Eat a nutritious diet. Include vegetables, fruits, greens, nuts, dairy products, fish, and eggs in your diet. Take the iron tablets and calcium tablets prescribed by your doctor on time.
• Drink plenty of water: Drink at least 2-3 liters of water a day.
• Exercise: Do light exercise. Things like walking and swimming are good. But ask your doctor before starting a new exercise routine.
• Get enough sleep: Get enough sleep. Try to get at least 7-8 hours of sleep a night. It's good if you can get some rest during the day too.
• Mental health: Be happy. If you feel overwhelmed, talk to someone you trust. Share these experiences with your husband and family.
• Talk to your baby: Now that your baby can hear your voice, talk to him, sing songs, and rub his belly. These things will strengthen the bond between you and your baby.

Remember: If you experience abnormal vaginal bleeding, severe abdominal pain, leaking amniotic fluid, or fever, you should see a doctor immediately .
