Baby Development

This week is the official start of your fifth month of pregnancy. Your baby is already capable of feeling and hearing. Now all he can hear is his heart and the noises of his digestive system.

Pregnancy

  • The baby’s head and body are now more proportional to each other and the facial features are practically defined and will not change until birth. At the 2nd ultrasound or morphological ultrasound (performed between weeks 19 and 22) you can look for physical similarities with the family and find out the gender of the baby
  • The skin looks reddish and the body is still very thin. In the coming weeks, the baby will devote himself to accumulating fat under the skin
  • The eyes are properly positioned and directed forward
  • The soft cartilage of the body gradually transforms into bone and the muscles begin to emerge. The baby has plenty of room to move around. This movement is essential for good muscle, joint and bone development
  • Fingerprints are formed at the tips of the fingers
  • The intestines begin to produce meconium (the baby’s first fecal matter)

Do not forget to inget calcium

Throughout the pregnancy it is necessary to ingest much calcium. At snack time, you can eat almonds and bits of cheese. Make vitamins with natural yogurt and add sesame to meals may not look like it, but it is rich in calcium. Avoid soft drinks because the phosphorus contained in them impairs the absorption of calcium and can still cause cramps. Opt for coconut water or some juice, avoiding artificial sweeteners.

Week 18 – 3rd Day

Paternal Insecurities

Even if they do not say it, many men are afraid that after the baby arrives, their partner will forget about it and focus all their love and attention to the newborn. “Will she still like me after the baby is born?” Give him confidence right away with words and gestures and explain that both father and mother will focus heavily on the baby’s needs. When the baby is born, try to set aside time for the couple. Your child will completely change their routine, now it’s time to prepare for it, remembering that the presence of the child’s father is very important since the pregnancy.

Week 18 – 4th Day

Body Temperature

Throughout the pregnancy, it is not recommended to use saunas, hot tubs or hot tubs (with a temperature above 30º). The body temperature of the mother can harm the fetus. This is also true when doing physical exercises you should take care that your body does not get too hot. Another reason to stay away from hot environments is that pregnant women have a natural tendency to hypotension (low blood pressure) and are more susceptible to fainting.

In this position, the ideal is for the woman to be walking.
