At this point in a pregnancy it is important to follow the schedule of ultrasounds to ensure that the fetus is growing properly. It is also convenient to start thinking about exercises that can facilitate the moment of delivery, but for this there is still time.

This month marks the end of the second trimester of pregnancy, an advanced stage since more than half of the whole process of gestation has passed. Next we will analyze the stages of maturity of the fetus in the womb.

General changes

During this month the baby is able to open his eyes and, although his vision is not yet formed, he is able to distinguish light changes. Other important changes that occur in the baby are the appearance of hair, eyebrows and eyelashes.

  • Your child grows from about 27cm in length at the beginning of the sixth month of pregnancy to about 32cm. In average, the baby grows 4 to 7 cm.
  • The baby’s weight increases about 300 grams. The baby weights 450 grams at the beginning of the month and 750 grams at the end.

The size of the umbilical cord makes it easier for the baby to move and for his muscles to grow. For this reason you will notice that the baby moves with much more energy. You can stimulate the child with music as he or she responds to loud sounds.

Tips for pregnant women

Even though every pregnancy is different it is also true that there are certain general patterns that repeat in almost every woman, as is the case of nauseas. For this reason, it is possible to advise the future mothers who are in the sixth month of pregnancy:

  • Increase the amount of zinc in the diet.
  • Avoid drinking liquids right after getting up.
  • Avoid foods that are conserved or high on fat and drinks that are too sweet.
  • Try to ventilate closed spaces. A pregnant woman can more easy perceive smells and feel nauseated because of them.

Sixth month of pregnancy by week

Find all the details about each one of the weeks that conform month 6 of pregnancy below.

Week twenty-one of pregnancy

In this week the baby already breathes and swallows amniotic fluid and is preparing for when he is born and has to survive in a very different environment. Furthermore, the baby moves every 1 or 2 minutes and you will be able to continuously feel his movements. It is also important to note that after this week the baby’s bone marrow is already formed.

Week twenty-two of pregnancy

Back pain is very common at this advanced stage of the pregnancy when the baby weights almost 400 grams. The limbic system of the fetus is in full development and his skin, that is still thin and colored, is covered with vermix.

Week twenty-three of pregnancy

It is important to try to gain weight regularly but without overcoming the standard values.

The mother’s weight gain should be reasonable and stable. An excessive weight gain during pregnancy is neither good for the mother nor the baby.

Blood flows through your body in a different way and you may feel that your legs are more tired and sensitive than usual. Normally, you do not have to worry about this.

Week twenty-four of pregnancy

Your uterus is stretching and so is the skin of you abdomen. For this reason, besides back pain you might feel itchy. Don’t forget to use some lotion in order to avoid stretch marks. The baby grows stronger every day and you can feel his kicks.
