Your baby is about 4 inches from the top of their head to the bottom of their spine and weighs more than 1 ounce. They’re about the size of a lemon.

This week, your baby:

  • Makes facial expressions.
  • Moves almost continuously.
  • Holds their head up straight.
  • Starts growing hair on their head and eyebrows.
  • Has fully developed external genitals.
