Inside The Womb

Baby's Development

The baby is shedding the rest of the vernix and lanugo, which they swallow. This forms their first bowel movement (meconium) after birth. The baby's ears are fully formed and sensitive to sounds.

Weekly Milestones

  • Fetal Lightening / Dropping
  • Hearing Fully Sensitive
Maternal Health

Your Body & Symptoms

The baby may 'drop' or descend into your pelvis (known as lightening). This makes it easier to breathe and eat, but increases pressure on your bladder and hips, making walking uncomfortable.

Common Symptoms this Week

Lightening (baby drops) Pelvic discomfort Frequent urination Braxton Hicks

Doctor & Care Recommendations

  • Enjoy the ability to breathe easier, but take short steps if walking feels unstable.
  • Prepare your post-partum care station at home.
  • Keep your hospital bags by the door or in the car.
