What's Happening With Your Baby This Week?

  • Nutrient flow through the umbilical cord is beginning to slow; the placenta has entered its aging process.
  • The placenta is nearing the completion of its duty; it's transferring the final antibodies the baby needs.
  • Surfactant production in the lungs is at full capacity; everything is ready for the first breath.
  • Brain development will continue rapidly after birth; however, the basic structures are fully formed.
  • The baby is in its tightest position in the womb; legs pulled to the belly, arms against the chest.

This Week's Tips for Mom

  • Contractions may become more frequent; try to distinguish between real labor and Braxton Hicks.
  • Keeping your mind calm is very valuable; meditation and visualization techniques can help reduce labor anxiety.
  • Light walks can support your pelvic muscles; gravity can help the baby descend.
  • No special nipple preparation is needed before birth; if your nipples crack after birth, lanolin cream can be soothing.
  • Saving emergency numbers (doctor, hospital, ambulance) to your phone's home screen is a great idea.
Tip of the day: If your water breaks (amniotic fluid release), even if you're not in pain, contact your doctor and head to the hospital right away. The fluid is usually clear and odorless; it's important not to delay in order to prevent the risk of infection.
