A baby grows in its mother’s uterus (womb). During the first 8 weeks after fertilization, the baby is called an embryo. After 8 weeks, the baby is called a fetus.
When a woman becomes pregnant, her body begins the amazing process of growing a baby. The baby starts out as a tiny ball of cells and grows quickly into a human being. By the end of the pregnancy, the baby is about 20 inches long and weighs 7 pounds.
The baby grows inside the mother’s womb (uterus), attached to the mother’s blood supply by the umbilical cord. The placenta is a flat, round organ that develops in the uterus during pregnancy. It provides oxygen and nutrients to the growing baby and removes waste products from the baby’s blood.
The average pregnancy lasts 40 weeks, or just over 9 months. During this time, both the mother’s body and the baby go through many changes.
9 Month Baby in Womb Video
A nine-month baby in the womb is the size of a watermelon. The average nine-month fetus weighs seven pounds and is about 20 inches long. The majority of fetal growth occurs during the last trimester, when the baby gains about two pounds per week.
During this time, the baby’s brain and nervous system continue to develop, and the lungs mature in preparation for breathing after birth. By the end of pregnancy, most babies have settled into a head-down position in their mother’s pelvis, ready for delivery.

How Does a Baby Form in the Belly?
A baby starts to form when an egg is fertilized by a sperm. The fertilized egg then implants itself in the lining of the uterus. Over the next nine months, the baby grows and develops inside the mother’s womb.
The baby’s heart begins to beat about 21 days after conception. By week six, brain waves can be detected. Arms, legs, eyes, ears, nose and mouth begin to form during weeks eight through 12.
At week 20, the baby is about 8 inches long and weighs about a pound. He or she can now yawn, hiccup and suck his or her thumb. During the final weeks of pregnancy, fat continues to build up under the skin.
The lungs are not fully developed but they practice “breathing” movements by expanding and contracting.
Where Exactly is the Baby in My Stomach?
Assuming you are referring to the placement of a fetus during pregnancy, according to Healthline, “By the end of the fourth week of pregnancy, your baby is about 1/4 inch (6.35 mm) long — about the size of a lentil. The embryo’s heart begins to beat around this time.” At eight weeks, “your baby is now called a fetus and measures about 2 inches (51 mm) from head to bottom. She weighs less than 1/8 ounce (about 3 grams). Her body is beginning to straighten out.” The location of the fetus changes as pregnancy progresses and the womb expands.
By 20 weeks, “the average baby is about 10 inches (255 mm) long from head to bottom and weighs about 1 pound 4 ounces (567 grams). She’s also starting to fill out — her arms and legs have plumped up.” Full term is considered anywhere from 38-42 weeks gestation.
