Third Trimester: The Baby at 37 to 40 Weeks
  • By the end of 37 weeks, your baby is considered full term. Your baby's organs are ready to function on their own.
  • As you near your due date, your baby may turn into a head-down position for birth. Most babies "present" head down.
  • At birth, your baby may weigh somewhere between 6 pounds, 2 ounces and 9 pounds, 2 ounces and be 19 to 21 inches long. Most full-term babies fall within these ranges. But healthy babies come in many different sizes.
