17 Week Pregnant – Baby Development

  • At 17 weeks, your baby weighs approximately 5 ounces and measures around 5 inches in length, roughly the size of your palm.
  • Fat tissue development begins in specific areas such as the face, neck, breast, and stomach wall before gradually spreading to the back, shoulders, arms, legs, and chest.
  • Muscles and bones continue to grow and strengthen, supporting your baby’s overall development.
  • At 17 weeks, tiny toenails are beginning to sprout on your baby’s feet, adding to their growing list of adorable features.
  • Additionally, a protective film called vernix forms on your baby’s skin. Vernix acts as a natural moisturizer and helps to protect delicate skin from the amniotic fluid.
  • Your baby can make sucking movements with their mouth and may start drinking the amniotic fluid. 
  • The umbilical cord is growing denser and longer to deliver nourishment to your baby, while the placenta is expanding and enhancing circulation to deliver essential nutrients and oxygen to support your baby’s growth and development.

Seventeen weeks of pregnancy is approximately 4 months and 1 week. Pregnancy is generally divided into three trimesters, each consisting of three months. Therefore, at 17 weeks, you would be in the second trimester of your pregnancy.
