The Baby

Week 26

Your baby might be kicking a lot during this period and might even be wak-ing you up at night. It weighs around 910 grams – 1 kg and it’s height from the head to the hips is about 23 cm. 

There is still a lot of room in your uterus, so the baby can move as it likes. You can try to get into a specific position that’ll help you sleep more comfortably and body pillows are a great solution for this time.

Week 27

Your baby’s size can now be measured from head to toe instead of from head to buttocks. This week, it’s nearly 40 cm tall. The baby has more taste buds in its mouth at this moment, than it’ll have at the time of its birth. This means that it can not only recognize the food you eat through the amniotic fluids, but also react to it. For ex-ample, some babies might respond to spicy foods with hiccups or kicks.

Week 28

The baby is now 35-40 cm tall and weighs around 1100-1300 grams. Of course, the height and weight of each baby can be different, just as they have different growing curves after birth. These numbers usually refer to average statistics, and they do not mean that there is something wrong with your baby if it’s heavier or lighter. If your doctor doesn’t see any issues with the growth curve, everything should be okay.

Your baby’s eyebrows and eyelashes form at this time and it can blink its tiny eyes.

Week 29

Studies show that babies who are born in the 29th week have fully devel-oped senses of taste and smell and partially developed senses of light. Even though your baby has a relatively developed immune system at birth, the antibodies (the weapons that drive away any foreign cells from the body) in your breastmilk will protect it from infections. Your baby now falls asleep and wakes up regularly, but it’s sleep schedule doesn’t resemble a newborn’s. It sleeps for about 20-30 minutes in each cy-cle.

Week 30

This week your baby gains the ability to see and distinguish between dark-ness and light. And to think it was as big as a sesame seed only yesterday… It takes up more and more space in the uterus and the amount of amniotic fluid is decreasing. Your baby is getting really settled in your stomach, gaining weight and becoming so beautiful.

Week 31

Your baby weighs around 1500-1600 grams and its tiny body is about 40-45 cm tall.


These weeks are more about weight gain than growing in size. Your baby’s lungs and digestive system is almost fully developed. Its pupils can dilate and constrict with light. The baby moves regularly during the day and it can now hear and feel. You can talk to your baby, introduce it to the people you love and bring it together with peo-ple who will be by your side during the birth.

Week 32

Your baby spends 90-95% of the day in sleep. Its hair is grown out now, which makes some women start feeling nauseous again. The wrinkles in your baby’s face begin to diminish. It keeps practicing some movements such as kicking, sucking, swallowing and breathing, which will be useful to it once it’s born. These days your baby could also be trying to position itself toward the birth canal, meaning head down (I hope).


Week 33

As the amount of amniotic fluid decreases, the baby will begin to move less. The baby’s brain keeps developing and the circumference of its head increases. Its skin continues to store the fat that causes the pink color change. All the bones in the baby’s body keep hardening with the exception of the bones in the head, which need to be flexible for the birth.

Week 34

Your baby will be born soon and it’s gaining more weight, so it now weighs about 2200 grams and is 44-50 cm tall.

Your baby now closes its eyelids when it falls asleep and opens them when it’s awake, just like a newborn. It can hold objects with its hands now. This week sees seri-ous development in lungs and other organs, therefore, even if you give birth this week your baby will probably be able to breathe on its own.

Week 35

Your baby’s hands and feet become chubbier as the fatty tissues keep growing. After this week, the baby takes up a lot of space in the uterus and doesn’t have a lot of wiggle room. So if you are not feeling too much movement, that is why.

Week 36

The baby is almost completely developed beginning from this week, so whenever it decides to come out from now until week 42, it can survive and live a healthy life without needing to stay at the NICU. Its immune and digestive systems are developed and it’s gaining weight nicely. It weighs about 2750 grams and is probably 46-51 cm tall.

Week 37

Your baby might be practicing its breathing now because it’ll be born very soon and it needs to get used to breathing. It’s lungs are almost fully developed, so it won’t even be considered premature if it’s born anytime beginning from this week. Still, if it can stay in your belly a bit longer, its development will be complete, so the decision is the baby’s. The baby now can turn towards any light or sounds that come in. It is also gaining more weight and getting chubbier every day. The immune system that will pro-tect your baby against infections is developing as well and your breast milk will be the biggest contribution to that. Breast milk supports the immune system with the sub-stances and antibodies it contains.

Week 38

Your baby weighs around 3.1 kilograms and is about 47-50 cm tall. 

The weight gain slows down and the circumferences of the head and the stom-ach are nearly equal. Most of the lanugo hair that covers the baby’s skin is gone and the waxy white layer (vernix caseosa) has almost disappeared. The baby swallows some of that layer and that will form the first black stool that your baby will produce.

Week 39

Your baby sleeps a lot. As the immune system completes its development, the baby continues to get antibodies from the mother through the placenta. There is not much left to say as things come to a conclusion… The baby’s growth slows down; it weighs 3000-3600 grams and is 48-53 cm tall.

Week 40-41

Your baby now weighs 2700-4000 grams and is 48-56 cm tall. It’ll be born any day now. When you meet your baby, remember to talk to it and say “Wel-come,” because it’ll be able to recognize your voice and its father’s voice AND your words will be the first that your baby hears in this world… It’s up to you to make sure your baby starts its life feeling safe and loved.
