Growth of Baby in Pregnancy Week 13

  • By the end of the 13th week the baby is fully grown. The head is still bigger than the rest of the body
  • The baby measures approximately 2-1/2 to 3 inches and its weight is nearly an ounce
  • The baby will have its first bowel movement i.e. meconium
  • Intestine and other organs are finding their places inside the baby's growing body. For example the eyes of baby come closer
  • The bones are still soft and flexible
  • The placenta is functioning fully i.e. providing the required oxygen, minerals, vitamins and proteins to the baby.  In addition to this, the placenta also keeps the baby away from carbon dioxide and the body waste of the mother
  • A 13 week baby starts moving around in the uterus

Since the baby is dependent on your diet, it feeds on whatever you eat. It is not only that the nutrients that are carried to baby but the unhealthy stuff can be carried to the baby as well. So stay away from alcohol, caffeine and any harmful medication.

Pregnant women may develop a condition called incompetent cervix, a condition caused by swelling in the cervix.  Incompetent cervix can even occur due to cervical trauma or congenital disorder.  At this stage it is vital for mother to take vitamins and plenty of milk
  • Since the body is preparing for lactation the breast size will continuously increase
