Third Trimester of Fetal Development

My wife is pregnant right now, so he wanted to know the development of the fetus from month to month. After searching for information for some time, I finally found it. This is information that I found:

7 Months pregnant, end of week 28

Length: 9.8 inches (250 mm), top to bottom
Weight: 2.1 pounds (950 g)

  • For most of this month, a fetus is putting on a lot of weight.
  • At this size, a fetus can still move around a lot—from head-down to feet-down, or even sideways. You will notice more movement or less movement at certain times of the day and night.
  • At about 24 weeks of pregnancy, the lungs are starting to make surfactant, which helps the lungs breathe air.
  • With every week after 22 weeks, a baby is a little more likely to survive after birth. A baby born before 26 weeks is not yet equipped to breathe air. Starting at week 26, the chances of healthy survival get better.
  • Around 28 weeks, the eyelids are open, hair is growing well on the head, and fat under the skin is making the skin less wrinkly.

Length: 11.8 inches (300 mm), top to bottom
Weight: 4.4 pounds (1995 g)

  • The fetus is putting on a lot of weight this month.
  • At this size, a fetus is still small enough to change position a lot—from head-down to feet-down, or even sideways. You will notice more movement or less movement at certain times of the day and night.
  • By 32 weeks of pregnancy, light can dilate the pupils in the eyes.
  • The lungs and central nervous system are working well enough that a baby born this month can breathe and keep fairly warm with medical support. With every additional week, the chances of healthy survival get better.

9 Months pregnant, end of week 36

Length: 12.6 inches (320 mm), top to bottom
Weight: 5 pounds (2300 g)

  • Until week 36 of pregnancy, your fetus is probably still small enough to change position a lot—from head-down to feet-down, or even sideways. You will notice more movement or less movement at certain times of the day and night.
  • By the end of this month, the skin is pink and smooth. The arms and legs look chubby.
  • If your baby is born at a healthy weight during this month, chances of healthy survival are very good.

Full term, end of week 40

Length: 14.2 inches (360 mm), top to bottom
Weight: 7.1 pounds (3230 g)

  • Your baby is full-term when you have finished 37 weeks of pregnancy.
  • By the time a baby is born at term, fat makes up 16% of body weight. The baby's growth has slowed in the last days before birth.
  • At this size, your baby does not have much room to move around. You will probably notice less "big" movement than before.
  • Your pregnancy is called "post-term" or overdue when you have finished 42 weeks of pregnancy. This is 2 weeks after your due date. Risks go up for the baby, so delivery is recommended.
