Week 33

In these last few weeks before delivery, billions of your baby's brain cells are helping her to learn about her environment. These cells help her to listen, feel, and even see. In fact, this is another important week for visual development. By now, your baby may now be able to experience her surroundings visually, since the pupils of her eye can now detect some light. Her pupils are constricting and dilating to allow her baby to see dim shapes.
Your baby now weighs about 4.4 pounds! (Babies gain a good deal of their weight in the final few weeks before birth.) She is about 16.4 inches long from head to toe.
Other developments this week include:
* Baby's head size will increase about 3/8 of an inch in circumference this week.
* Baby is now sleeping much of the time.
* Baby's lungs are continuing to mature.
* Fat will continue to be added on to Baby's body for protection and warmth.
* The testicles of most boys have by now moved into the scrotum. (verybestbaby.com)
