Update on Jacob's developement

What Jacob was up to last week: 22 week update

Eyelids and eyebrows are fully formed.
Fingernails have grown to the end of the fingers.
Be prepared for all those "Why" questions coming! Your baby's brain has entered a stage of rapid growth, especially in what's called the germinal matrix. This structure deep in the middle of the brain serves as a kind of factory for brain cells and disappears shortly before birth. But the brain's amazing expansion program continues until around the five birthday.
With some help from mom, baby's liver is starting to break down bilirubin, a substance produced by red blood cells.
If your baby is male his testes begin their descent to the scrotum.
Primitive sperm have formed and he is producing testosterone.

If born now, your baby has a 15% chance of survival, his odds going up with each passing day. .
The average baby at this stage weighs 1.1 pound and is 11.38 inches long.
