During these weeks, pregnant women tend to put on half a kilo every week. It’s the moment when the baby grows the most and when he gains weight, he will increase approximately half of his weight (250 grams).

The increase in weight and volume may provoke that you feel tired easily. During the final stage of pregnancy the gravity centre changes, the ligaments and muscles of the abdomen expand and may put pressure on some nerves, which may provoke that you feel a stabbing pain or a painful sensation, especially in the area of the lower back and the hips. If the pain is severe, you feel a tingling sensation in your legs or you feel that your limbs don’t react when you want them to, go to the doctor.

The baby will have grown a lot, which means that your organs have every time less room. The stomach doesn’t have a lot of space. That’s why, from the 32 week, on it’s advisable not to eat big meals but with a higher frequency. You should eat six times a day approximately. This way, you’ll manage to reduce acidity and your digestions won’t be so heavy. The situation of the lungs also has changed, that’s why you may feel short of breath or you get tired easily. Avoid physical efforts that accelerate your breath.

Foetal brain 32 weeks

Your son is now fully formed, but he doesn’t count on big reserves of fat under his skin. If he was born now, he would need to spend some time in the incubator.

His bones are completely developed, even though they are still flexible and soft. His body begins to stock up calcium, iron and phosphor. The brain is formed and there are no differences between how it is now and the one from the moment of birth.

If he is a boy, his testicles, which started descending on week 12, will now displace through the inguinal conduct, until they reach the scrotum on week 32.

As for the size, he will weight approximately the half of what he will weight at the moment of birth. That will be 1,800 grams approximately, and he will be 42 cm long.

If the weight of your child is located between 1,300 and 2,375 grams, don’t worry, they are also considered normal values.
