Baby at 16th Week
A week is a short time for you, but it is a long time for your baby… Even in such a short time, he has acquired many new skills. what? Let’s take a look at the details you need to know about the 16-week-old baby…
How Big Has My Baby got?
Your little one continues to undergo serial mitotic divisions, thereby increasing the mass, length, and size of their organs. In the face of this rapid change and development, the weight and height of the 16-week-old baby, which reached the size of an avocado, almost reached the following values.
Development of Systems and Newly Acquired Skills
The changes in the organ and system development of the 16-week-old baby, who transformed from a single cell into a complex creature with systems and organs, are truly astonishing.
The skull grows to make room for the brain to increase the number of cells. While the brain grows easily in this way, the sense organs and other organs under the control of the brain continue to develop. With this development, the baby will be able to communicate by receiving stimuli from the outside world even while in the mother’s womb.
The spinal cord develops and in parallel with this, reflexes such as catching, sucking, swallowing, which are under the control of the spinal cord, begin to show themselves.
The circulatory system
The baby’s blood volume increases and the heartbeats are harder to pump blood through the veins. It expends a serious amount of energy by beating about 140-150 times per minute.
The structures and organs that make up the digestive system were already formed in the previous weeks, now it spends its energy on maturation and gaining the capacity to digest food.
With the development of the swallowing reflex of the 16-week-old baby, he swallows the liquid he is in. The nutrients in the swallowed liquid are digested by being exchanged through the stomach and intestines. As a result of this simple digestion, a small amount of waste is produced and as of this week, wastes begin to accumulate in the colon. These wastes, called meconium, are the substance that will be the first poop of the baby after birth.
Although the last respiratory system will complete its development, there are important developments in respiration even at the 16th week of pregnancy.
Bronchioles begin to form. The baby, who takes it from the nose and fills and drains the liquid up to the bronchioles, is actually doing simple breathing practices. Even his chest rises and falls as if he is breathing. In this way, the fetus, which started to do regular breathing exercises, now knows how to hiccup. Not for now, but in the coming weeks, you will feel your pup’s hiccups.
Support and Movement System
Head from the structures that make up the skeletal system; larger than the trunk and legs. This rate will continue to grow by 1/3 for all three regions in the coming period.
The baby accumulates calcium in the cartilage structures and performs ossification. Muscles are getting stronger. Parallel to the strengthening of the muscles, the internal organs that work with the help of the muscles also gain functionality.
The spine straightens.
The kidneys and the adrenal glands (adrenal glands) located above the kidneys have increased in size enough to be visible on an ultrasound scan.
Structures in the kidney, called the glomerulus, filter the blood and form fetal urine and leave the urine into the placenta.
Internal reproductive organs in baby girls; The ovaries, fallopian tubes, and uterus are formed but need further development. The vagina becomes clear enough to be evident on ultrasound.
Internal reproductive organs in male babies; testicles, glands, and sperm duct developed. The penis, which is the external reproductive system organ, is prominent enough to be seen on ultrasound. The testicles have formed but have not yet descended into the upper abdomen and scrotum.
Regardless of male or female, “Will the gender of the 16-week-old baby is known?” If you say: Yes, it will be obvious. However, it is difficult to say exactly whether it is a girl or a boy yet. Because the baby may not stand in the right position, and the umbilical cord may confuse the doctor about gender. Therefore, it is normal for your doctor to want to wait a few more weeks to give a clear answer.
He has a simple immune system for now. This system is formed by dendritic cells, which are formed by the baby and develop a defense against foreign substances, and vernix caseosa, which prevents the baby from getting any infection from the amniotic fluid through the skin.
16 Week Baby Movements
In this time, your little one has grown enough to do somersaults, turn, and kick. It fidgets in the uterus, it can’t stay still. However, the 16-week baby movements are not as intense as you can feel yet. His bones need to grow a little more and his muscles need to get a little stronger. You will wait a few more weeks to witness this miracle.
Sensory Organs and Developmental Characteristics in 16 Weeks Baby
The brain controls the functioning of the sense organs. For this reason, your baby’s senses of sight, hearing, touch, taste, and smell are directly proportional to brain development. As of the 16th week of pregnancy, some of the baby’s sense organs have reached the level to function, albeit limited.
Let’s see how much the sense has developed in this process…
Eye and Sight
The eyes are far apart and not yet where they should be on the head. They have already set out to reach the place where the percentage should be after they were born, and they have already started to get closer to each other.
The eye muscles are able to move the eyes in their sockets, but the eyelids are still not developed enough to open and close.
Ear and Hearing
Ear protrudes enough to be evident on ultrasound at 16 weeks of pregnancy but is not yet where it should be on the head
Hearing receptors are rapidly increasing in number, but they are not yet at a level to detect sound waves. He needs a little more time to hear your beautiful voice.
Skin and the Sense of Touch
The skin quickly stores fat. However, he still has not accumulated enough fat to maintain his body temperature. For this reason, the amount of lanugo hairs that serve to insulate the baby’s body needs to be increased even more.
On the surface of the skin, eyebrows, eyelashes, and hair begin to grow. However, it is white in color because there are no color pigments yet.
The skin is transparent for now, and the internal organs are visible even from the skin surface. In the following weeks, as the baby stores fat under the skin, it will become chubby and form pink baby skin.
Sensory receptors developed on the skin of the palms, genitals, soles of the feet. The baby can perceive temperature, pressure, and similar tactile sensations in these areas.
Tongue and Taste
Taste buds form on the tongue. For this reason, the baby begins to taste the pyruvic acid, lactic acid, creatinine, urea proteins, and the food the mother eats in the amniotic fluid she swallows.
Nose and sense of smell
Olfactory receptors begin to form in the baby’s nose, called the yellow zone. Thanks to these receptors, your pup can smell the substances in the amniotic fluid entering his nose.
Mom at 16 Weeks Pregnancy
A single cell in your uterus; If it turns into a human baby that works flawlessly with all its systems, it means a lot is going on in your body. Of course, 16 weeks pregnant also feel all the changes in this process in the form of certain symptoms. What are these symptoms? Learning about why it occurs and how it will go about helps you get through the process with minimal damage.
Weight gain may not be experienced during the first 3 months of pregnancy. However, after the 3rd month, with the baby’s significant growth, the expectant mother begins to gain weight. So, 16 weeks old mother better switch to loose clothes with an elastic waistband or start buying maternity clothes for herself.
Itching and crack formation on the skin surface:
Since weight gain has begun, the skin must make room for new weights. If you gain weight at a rate that does not allow the skin to stretch, the skin makes room for itself by creating cracks. Stretch marks appear on the skin as pink, yellow, tan, or purplish-toned lines. Sorry, but these scars are permanent and will not go away after birth.
The increase in pregnancy hormones increases blood pressure and causes an increase in body secretions. The increased secretions accumulate in the cells and cause edema or an increase in secretions such as vaginal discharge, sweat, and mucus.
Pain in the lower back and legs:
The increase in the baby’s height and mass put an unfamiliar pressure on the mother’s body. Especially the waist and legs, which carry the weight, are affected by this extra weight and pain occurs.
Heartburn and indigestion:
The muscles that enable the digestive system organs to work slow down with the effect of pregnancy hormones and indigestion occurs. On top of that, when the weight of the uterus becomes heavy, acidic foods that have become slurry in the stomach go back to the esophagus and mouth. So reflux occurs.
Hemorrhoids are one of the most common pregnancy symptoms during pregnancy. With the 16th week of pregnancy, hemorrhoids begin to appear as a result of the weight of the uterus. While the uterus becomes heavy and presses on the intestines, pregnancy hormones relax the intestinal muscles. All these cause the intestine to be pushed out of the body, that is, hemorrhoids.
Breast enlargement and tenderness:
Although you are in the 16th week of pregnancy, increasing pregnancy hormones begin to stimulate the mammary glands. The stimulated milk ducts swell, causing tension and tenderness in the breasts.
Tips to Minimize Annoying Pregnancy Symptoms!
Pregnancy is different in every period in terms of symptoms. Since the first trimester is the first time the body meets pregnancy; The second trimester is difficult for the mother as the birth is approaching. The second trimester is the middle of the two and is known as the golden age of the pregnancy. Yes, it is a little easier in terms of symptoms, but still, taking small precautions can make your golden age even more comfortable. To minimize the symptoms of 16 weeks of pregnancy, you can be careful about the following points.
- Just be careful not to snack and gain extra weight just because I’m pregnant. Controlled and slow weight gain reduces stretch marks, waist and leg pains, hemorrhoids and digestive problems by giving the skin the opportunity to stretch so that the body can expand.
- You can prevent the formation of stretch marks by keeping the skin moist with stretch mark creams or natural herbal oils.
- Eating at frequent intervals and little by little reduces the complaints of reflux, heartburn, and indigestion.
- If you do not want the swelling in the breasts to bother you too much, you can enlarge your bra size. In order to prevent the clothes from touching your chest and hurting, you can choose loose clothes.
How Much Weight Should I Gain?
While the baby is growing and developing rapidly, the mother is expected to gain weight after the first 3 months of pregnancy. Since you’re 16 weeks pregnant, you’ve just passed 3 months, and being overweight already creates problems in the future. Both your pregnancy symptoms will be more severe and it will be difficult to regain your old weight after delivery.

In other words, being careful about nutrition at 16 weeks of pregnancy is necessary for the health of both the baby and you. For this reason, it is necessary to be careful about the following points.
- Don’t eat for two just because I’m two creatures. It is enough for you and your baby to take only 300-350 calories more than the amount you normally eat.
- The 16-week-old baby uses the mother’s calcium reserves to ossify the cartilaginous skeletal system. The decrease in the mother’s calcium reserve causes tooth loss and skeletal system pain in the mother. Therefore, make a habit of consuming calcium-rich foods such as seeds such as poppy, sesame, almond and chia, sardines, salmon, beans, lentils.
- Drink plenty of water, not less than 2 liters a day.
- Feeding at frequent intervals and little by little reduces digestive system disorders such as reflux, hemorrhoids, and constipation.
