My group did sex determination. As a supplement, I did the time line for fetal development. Starting in the first month of pregnancy, I went all the way through to the ninth and final month, when the baby is born. Some key points were:

__First - Third Month__ __Fourth - Sixth Month__ __Seventh - Ninth Month__
 * By the end of the first month, your unborn baby is technically known as an embryo.
 * By the end of your first 6 weeks of pregnancy, the baby has a head and trunk, and is about 1/4 inch long (8 mm) and weighs a fraction of an ounce (or a few grams).
 * The baby’s development is rapid in the second month.
 * By the end of the second month, all of the baby's major body organs and body systems, including the brain, lungs, liver, and stomach, have begun to develop
 * By the end of the second month, the sexual organs begin to grow and it is then graduated to the term fetus
 * The baby is completely formed by the end of the third month.
 * It may have begun moving its hands, legs, and head and opening and closing its mouth, but he or she is still too small for you to feel this movement.
 * The tail has disappeared from the fetus and the head makes up about half of the baby's size.
 * By the end of the fourth month, the baby will be 5 to 6 inches (13 to 15 cm) head to rump in length and weigh about 5 ounces (about 140 grams).
 * This is a period of huge growth for the baby.
 * The internal organs are maturing. Fat is now being stored beneath your baby's skin. The blood cells take over for the liver the job of producing blood. It’s gall bladder will become functional, producing bile that is necessary for digestion.
 * Baby is now about 7 inches (17 cm) Crown to Rump, about 10 inches (25 cm) from head to heel.
 * Baby weighs roughly 11 ounces (about 300 grams).
 * This month continues to be a period of rapid growth.
 * By the end of the sixth month, your baby will be around 11 to 14 inches (28 to 35 centimeters) long and will weigh about 1 to 1.6 pounds (500 to 750 grams).
 * If the baby was born now, its chances of survival are better than last month, (28 weeks - 90% of babies survive premature birth) some complications are still possible. By the end of this month, the baby is approximately 16 inches (42 cm) long and weigh about 2.5 or 3 pounds (1100 to 1400 grams).
 * The baby will be having strong, regular fetal activity. At the end of this month the baby is about 16 to 18 inches (40 to 46 centimeters) long and weighs around 4.5 to 5.5 pounds (2 to 2.5 Kg).
 * The baby is fully formed
 * The baby prepares for birth with its head down against the birth canal, its legs tucked up to its chest, and its knees against its nose. The bones of baby's head are soft and flexible to ease the process of delivery through the birth canal.
 * The baby's lungs are now mature and it will have a great chance of survival if born a little early. It is now about 20 inches (51 cm) long and weighs approximately 6 to 9 pounds (2700 to 4000 grams). Only 5 percent of babies are born on their due date.
 * The baby may be born anytime between the 37th and 42nd week of pregnancy.
