How is your baby's development this week?

Now your baby is almost fully grown and ready to enter the world. Just imagine, you'll be able to hold him in your arms in no time!

Baby's weight and body size

By now, your baby weighs about 2900 grams, which is about 2.9 kilograms . Some babies may be a little heavier or a little lighter. That's normal. The height is about 34 centimeters, if you measure from the head to the buttocks. But the full height is much longer, about 48-50 centimeters.

This week, the baby's body is also accumulating more fat . This layer of fat helps the baby regulate its body temperature after birth. However, the baby is not growing as fast as it was in previous weeks. The growth is a little slower. The reason for this is that the baby is now more ready to come out.

Let's learn about the baby's intestines and first stool (Meconium)

Remember when we talked about the baby now sucking the amniotic fluid , the fluid that surrounds the baby? This isn't the baby's main source of nutrition, but it's how the baby learns to swallow and breathe. So, that amniotic fluid is mixed with cells from the intestines , dead skin cells, and the baby's fine hair called lanugo hair to form meconium .

Simply put, meconium is the baby's first stool. It is usually a dark green, black, sticky substance. It is the first thing that comes out of the baby's body within the first day or two after birth. Sometimes, before or during labor, the baby can pass some meconium into the amniotic fluid . If this happens, the color of the fluid will change. That is also something that doctors should take into account. Therefore, it is a good idea to pay attention to the color of the fluid when it passes.

  1. If you are having a baby boy (a son): His testicles are now fully descended.The testicles should be in the scrotum. Imagine how much goes on inside that little body! But sometimes one or both testicles may not have descended completely. We call this an undescended testicle . If this is the case, the doctor will talk to you about it after the baby is born and give you the necessary advice. Most of the time, it will completely go away on its own in a few months. Otherwise, you may need to undergo a little treatment.
  2. If you are having a baby girl: Her labia, or labia, are now fully developed.
  3. Lungs : The baby's lungs are now largely ready to come into the world. A special substance called surfactant continues to be produced in the lungs. This is what helps keep the lungs inflated like a balloon after the baby is born, making it easier for the baby to breathe on its own.
  4. Brain: Brain development also occurs rapidly in these last weeks. The brain continues to develop even after the baby is born. That's why we say that the first few years are very important for a baby's development.
  5. (Vernix Caseosa) and (Lanugo Hair): The white, thick coating called (Vernix Caseosa) and the fine hair called (Lanugo Hair) that was on the baby's body have mostly fallen off now. However, at birth, there may still be some in some places, in the folds of the skin. This is normal.
  6. Pelvic Pressure : The baby is now further down in the pelvis , so you may feel a lot of pressure on your lower abdomen, vagina , and back. This is called lightening . This may make it easier to breathe, but you may also need to urinate more often.
  7. Braxton Hicks contractions: Braxton Hicks contractions, or false labor, can feel a little more intense and more intense. They are not as regular as real labor and will go away after a while, either by changing positions or drinking a little water. They are like the body's training to prepare for labor.
  8. Back pain: Back pain is a common occurrence these days. Try to maintain proper posture as much as possible.
  9. Swelling: You may have some swelling in your hands and feet. But if it suddenly becomes very swollen, if your face also swells, if it is accompanied by symptoms like headache and blurred vision, it could be a sign of a dangerous condition called preeclampsia. If that happens , you should see a doctor right away. It is not something to be trifled with.
  10. Insomnia: With all these discomforts, it can be a bit difficult to get a good night's sleep. Try sleeping on your side as much as possible, with a pillow between your legs.
  11. (Nesting Instinct): You're feeling a strange urge to clean the house, prepare the baby's things, and decorate the room these days, aren't you? That's called (Nesting Instinct). It's also very normal. It's a way for mothers to prepare to welcome their baby. But remember, don't overdo it.
  12. (Mucus Plug) and (Bloody Show): The (Mucus Plug), which is the mucus plug that used to cover the cervix, can now be shed. It can also be mixed with a little blood and appear as (Bloody Show). This often means that there are still a few days or hours until labor. Not everyone sees this, so keep that in mind.
  13. Real Wednesday:
  14. This pain gradually becomes more severe and more frequent.
  15. The interval between two contractions gradually decreases (e.g., one that was present every 10 minutes, now occurs every 5 minutes).
  16. The duration of a single pain episode gradually increases (e.g., one that lasted 30 seconds becomes 45-60 seconds).
  17. Changing positions or walking does not relieve this pain, and may even worsen it.
  18. The pain usually starts in the back and travels to the abdomen.
  19. Water Breaking:
  20. A lot of fluid can leak out all at once, or it can leak out gradually. This is called amniotic fluid. It is usually clear and doesn't smell like urine.
  21. If this happens, even if there is no pain, you should go to the hospital immediately because the baby is now at risk of infection.
  22. (Bloody Show): As mentioned earlier, the mucus plug coming out with blood is also a sign that labor is near.
  23. If your water bag breaks.
  24. If the contractions come about every 5 minutes, if there is one pain for about a minute, and if it comes like this for about an hour straight (if this is the first baby, if it is the second baby, it may go earlier).
  25. If you have heavy bleeding (more than your normal menstrual period).
  26. If you feel that your baby's movements are very few, or if you feel that the pattern is different than usual.
  27. If you have a severe headache, blurred vision, sudden severe swelling of the face/hands, severe pain in the upper abdomen, or a fever.
  28. Hospital Bag: Your hospital bag should be by the door by now. Double-check that it contains everything you and your baby will need, including clothes, toiletries, important documents ( Antenatal Record, ID), and phone charger.
  29. Mental preparation: This is a life-changing experience. You may feel a little scared, anxious. These are all normal feelings. Stay strong. Talk to your husband and family. Follow the advice of your doctor. Practice relaxation techniques.
  30. Rest: Get as much rest as possible. You may be feeling very tired right now. It would be great if you could take a nap during the day.
  31. Light exercise: If your doctor has given you permission, do light exercise like walking. It will make your body a little easier and will also help with labor.
  32. Nutrition: Don't skip out on eating nutritious foods. Include foods high in fiber (whole grains, vegetables, fruits), iron-rich foods, and calcium-rich foods (milk, yogurt) in your diet. This will also help prevent things like constipation.
  33. Water: Drink plenty of water. You should drink at least 8-10 glasses of water a day.
  34. (Kick Counts): Keep an eye on your baby's movements. Do (Kick Counts) at a specific time each day. See if your baby moves at least 10 times in two hours. Tell your doctor if you notice any changes.
  35. Perineal Massage: Some doctors recommend perineal massage, which involves gently massaging the area around the vagina. It is said that this can help reduce vaginal tearing during childbirth. Talk to your doctor about this.
