The baby is beginning to descend into the birth canal (pelvis).

What's Happening With Your Baby This Week?

  • The head is settling into the pelvic bone; this is called "engagement."
  • Since space is very tight, you may feel more stretching and pushing movements rather than kicks.
  • The lungs are nearly fully mature; surfactant production has reached sufficient levels.
  • The digestive system is fully functional; meconium is stored in the large intestine.
  • The baby keeps storing about 14 grams of fat per day; energy reserves are building.

This Week's Tips for Mom

  • As the baby drops lower, your stomach will feel relieved and breathing will become easier.
  • However, pressure on the bladder will increase, so you'll need to urinate more frequently.
  • Doctor visits will now be weekly; cervical examination may begin.
  • Group B streptococcus (GBS) testing is done this week; the result may affect your birth plan.
  • Mapping out the route to the hospital and emergency plan with your partner is a great idea.
Tip of the day: Starting perineal massage can help reduce the risk of tearing and episiotomy during vaginal delivery. After consulting your doctor, you can gently massage with warm oil 2-3 times a week after showering.
