By this week, your baby`s crown-to-rump length is approximately 9.2 inches. Remember, that is only from the top of his head to his bottom and does not include his leg measurements! After a month of having his eyelids sealed shut, your baby begins to open his eyes again this week. Your baby`s eyes are almost completely developed. Your baby`s eyes are blue in the womb and may change colors later in life. This is true for all races because the iris doesn`t have its final color until a few months after birth. However, some babies are born with darker or lighter shades of blue. Your growing baby will continue to put on layers of fat until he is born. He is still lean at this point of the pregnancy though. By the time your baby is born, he will assume the typical newborn`s plumpness. Your baby`s skin will still be wrinkled and red, but the fat continues to fill the skin out.
