Believe it or not, your baby is the size of a raspberry and is growing at the rate of about 1 millimeter per day. That might not sound like much, but when it's happening every day, it adds up.
The baby's tiny little fingers and toes are forming, and the eyes are developing color. The beginnings of the baby's genitals are there now, but it's still impossible to tell whether it's a boy or a girl just by looking.
One of the most important developments is that the baby will start to move this week, but he's still too tiny to feel.
