Baby development – ​​27 weeks gestation

Pregnancy

In the 27th week of pregnancy, the baby’s development is marked by being able to open their eyes and having more regular phases of sleep and wakefulness, with rapid eye movements (REM) during sleep, which are important for processing memories.

Additionally, the lungs continue to mature and the baby may experience hiccups due to the breathing movements that help prepare the lungs for breathing after birth.

During this week, the woman may continue to have symptoms of cramps, swelling in the legs or feet, or Braxton-Hicks contractions, and hemorrhoids may appear.

Baby development

In the 27th week of pregnancy, the main milestones in the baby’s development are:

  • The baby’s brain is more active and neurons continue to form, making complex connections in all areas of the brain;
  • The eyelids are no longer fused, which allows the baby to open their eyes;
  • The baby now has more regular phases of sleep and wakefulness and when he sleeps, he already has rapid eye movements (REM), which is the phase of sleep that is important in processing memories.

The lungs continue to mature, the alveoli, which are small air sacs in the lungs, begin to expand and the baby may experience hiccups, but they do not make any noise because there is no air in the lungs.
