All senses are working busily. When you rub your belly, your baby may respond from inside.

What's Happening With Your Baby This Week?

  • Brain folds are deepening; these structures house more neurons, increasing intellectual capacity.
  • The baby has begun developing the ability to regulate its own body temperature.
  • Red bone marrow has fully taken over blood cell production; the liver is relieved of this duty.
  • Lanugo hair is starting to fall out; however, some may still be visible at birth.
  • Amniotic fluid keeps increasing; it usually peaks at around 800 ml to 1 liter in weeks 34-36.

This Week's Tips for Mom

  • Constipation may occur as digestion slows; fiber-rich foods and plenty of water are the most effective solutions.
  • Practicing breathing exercises would be wonderful; they'll be very useful during labor.
  • If back pain is increasing, you can try warm compress application and gentle stretching.
  • This might be your last chance to sign up for a baby care class; learning diaper changing, bathing, and breastfeeding techniques will build confidence.
  • Take preeclampsia symptoms (severe headache, vision changes, sudden swelling) seriously and contact your doctor immediately.
Tip of the day: To ease heartburn, try slightly elevating your head and shoulders with a pillow when sleeping. Stopping eating 2-3 hours before bed and avoiding spicy, acidic foods — these simple changes can greatly improve your nighttime comfort.
