As I said in the previous post, we are already in the second half of pregnancy in which the baby develops at an accelerated pace. We continue then reviewing the pregnancy calendar week to week.
Their organs are formed but they continue their maturation, perfecting themselves to function when they are born. In the next few weeks the baby will gain layers of fat that will give it a more plump appearance.
These weeks we go through the sixth month of pregnancy and as we usually do, we continue with the Baby growth review week by week.
25th week of pregnancy
In the week 25 During pregnancy, the baby is 23 weeks old, measures about 25 centimeters from the head to the buttocks, about 32 centimeters to the tip of the feet, and weighs about 700 grams.
Your skin is wrinkled but as it grows it will become smoother and softer. It is covered by a waxy substance called vernix that prevents it from cracking. The small teeth are located in their position under the gums, although there are still several months to see the first one sprout. Its head is covered with hair with color and texture, but neither one nor the other will be definitive.
At this point you will have noticed that the baby has periods of rest and periods of activity in which you can feel his movements, stretches and kicks.
Week 26 of pregnancy
In the week 26 It measures 34 centimeters to the heels and weighs 800 grams. His ears are perfected, so he reacts more consciously to the sounds that come from outside, and especially to your voice.
His eyes open and close intermittently, the baby practices the blink reflex and reacts to light stimuli, as well as sensory stimuli when you caress the belly.
Although oxygen still does not enter your small lungs because its medium is liquid, the baby performs daily breathing exercises.
As you gain weight, your body accumulates layers of fat that will help regulate body temperature outside the mother's uterus.
27th week of pregnancy
In the week 27 (25 weeks of the fetus's life) almost all eye structures are finished, although he is not yet able to see clearly, the development of the brain's visual zone allows him to distinguish lights and shadows.
Its size is 36 centimeters from head to toe and weighs about a kilogram. It looks similar to what it will have at birth, but thinner. From now on, your skin begins to thicken and gradually it will become smoother.
You can already clearly notice the baby's movements and you can also feel a kind of very characteristic rhythmic jumps when the baby has hiccups. It occurs due to the contraction of the diaphragm and although it can last for several seconds, fetal hiccups do not harm the baby but quite the opposite, it is a sign of good health.
28th week of pregnancy
In the week 28 The development of his lungs has great prominence. They begin to manufacture a substance called surfactant essential for breathing outside the uterus that prevents the alveoli from adhering to each other. Likewise, the lungs fill with blood vessels that will circulate oxygenated blood throughout your body and the bronchial tubes continue to divide.
At the end of this week, 38 centimeters long and weighing just over a kilo, it occupies almost all the space inside the uterus.
There are still twelve weeks of pregnancy calendar ahead, essential for the baby to complete its maturation, however if it were born now it would have a high probability of survival.
