Week 16 of Pregnancy: What's Going On Inside

Overview

By now, you may be looking a little more pregnant on the outside. And inside, your baby is starting to look more human and may even have sprouted a little bit of hair.

Wondering what your baby looks like at 16 weeks? Your baby is now about the size of an avocado. Average baby length is 4.7 in. (120 mm).

How your baby is changing

Here are some of the important facts and developments around 16 weeks.

  • This month, babies' faces have become more human. Their eyes have moved from the sides of their head to the front. Their ears have moved from the neck to the sides of their head.
  • By the end of 14 weeks of pregnancy, their sex organs are starting to develop. It will be a few weeks before an ultrasound will show the sex.
  • By now, your baby may have started thumb-sucking and is rolling, kicking, and moving around a lot.
  • If this is not your first pregnancy, you might be feeling your baby move. The first flutters you feel are called "quickening." It takes a little longer to notice this in a first pregnancy.
