Baby Development

As you baby develops, your body will change and so will your baby’s.

  • Month One: Your baby is like a tiny tadpole.
  • Month Two: A tremendous transformation takes place in your growing baby, still called an embryo, in the second month. All the major organs have begun to form by the end of the second month.
  • Month Three: The end of month three signals the end of the first trimester. The odds of miscarriage drop considerably at this point.
  • Month Four: Toward the end of this month you may experience the thrill of your first kick—most describe it as a flutter.
  • Month Five: You're probably feeling plenty of movement by now; enough to keep you awake at times. The fetus can turn from side to side or even head over heels. Fetal movement counts can help reassure you that your baby is doing well.
  • Month Six: Your baby continues to grow rapidly this month, and the organs continue to mature. Though the fetus has started breathing motions, the lungs are filled with amniotic fluid and are not yet fully developed or ready to breathe on their own.
  • Month Seven: Your fetus is acting more like a baby every day. She can suck her thumb, cry, and even hiccup. Her body is well formed.
  • Month Eight: Baby is really putting on the pounds now, gaining about a half-pound per week. She's so big that it's hard for her to move around, though she can still pack a wallop with that kick.
  • Month Nine: Though your baby isn't officially due until 40 weeks of pregnancy, she's considered "full term" after 38 weeks.
