With the most critical development behind the fetus, the chance of miscarriage drops considerably after this week.
At only 12 weeks old your baby is already silently crying inside you. By now his vocal chords are complete. Your baby can now even suck his thumb! The brain is fully formed, and your child can feel pain. But don't worry - he is as comfortable as a bug in a rug inside you.
Other significant developments include:
Those precious eyes begin to move closer together
Ears shift to their normal place on the side of the head
Intestines move farther in to your child's body
His or her liver begins to function - Responsible for cleansing the blood, storing nutrients, and providing needed chemicals, this is an important event!
