Your Baby's Development at Week 30 of Pregnancy

At week 30 of pregnancy, your baby can pee about a half a liter into the amniotic fluid every day!
Other fetal development that is occurring around week 30 of pregnancy includes the following:
  • In male babies, the testicles move from near the kidneys through the groin en route to the scrotum.
  • In female babies, the clitoris appears large and exposed because it is not yet covered by the folds of the skin called the labia.
  • The baby's head is getting larger.
  • The early lanugo is disappearing. There are still patches on the back and shoulders.
  • The eyelids open and close. Much of the time your baby has its eyes open and is looking around.
  • The bone marrow is now responsible for making red blood cells.
In preparation for breathing after birth, your baby will mimic breathing movements by repeatedly moving the diaphragm. These movements are rhythmic and may even cause your baby to get a case of the hiccups if amniotic fluid is accidentally inhaled. This is normal -- do not be concerned.
