Pregnancy Facts - Week 28

Your baby's development in week 28 of pregnancy

This week, your baby's ears are developing additional nerves to help transmit sound to the brain for interpretation. Did you know that your baby has been eavesdropping on your conversations since week 16 of pregnancy? Lucky for you, language comprehension is not one of the fetal developmental milestones and most of what your baby hears is muffled anyway. It's been demonstrated that babies can recognize voices heard in the womb after they are born. Go ahead and start talking to your baby to bond.


If you find that one-way conversations with your baby awkward, a device like belly headphones that can play music and voice recordings to your baby may be helpful.

Some additional tidbits:

  • This week, your baby's eyes open for the first time and blink.
  • Some may find it comforting to know that statistically, your baby's fetal viability is now greater than 92% at week 28 of pregnancy.
  • Did you know that at week 28 of pregnancy, the brain makes up about 12% of your baby's body weight?
