    Your baby is now about the size of a blueberry (and about 10,000 times bigger than he was at conception). Most of that growth is concentrated in the head as new brain cells are generated at the rate of 100 per minute. Your baby's mouth and tongue are forming as arm and leg buds sprout. http://www.whattoexpect.com/pregnancy/week-by-week/week-7.aspx

    Though he's barely the size of a kumquat — a little over an inch or so long, crown to bottom — and weighs less than a quarter of an ounce, your baby has now completed the most critical portion of his development. This is the beginning of the so-called fetal period, a time when the tissues and organs in his body rapidly grow and mature.

    By now, your baby weighs a full half-ounce and is about the size of a large plum. Most of his systems are in place, though there's still plenty of maturing to do. For one thing, his fetal digestive system is beginning to practice contraction movements necessary for eating, and his bone marrow is busy making white blood cells — weapons against germs once he's out of your safe haven. http://www.whattoexpect.com/pregnancy/week-by-week/week-12.aspx#

    about the size of an orange this week, her ears have migrated to the sides of her head, and her eyes are moving to the front of her face. Plus, your little smarty-pants can now wiggle her fingers and toes and make breathing movements in preparation for life outside the womb. http://www.whattoexpect.com/pregnancy/week-by-week/week-15.aspx

    Have you ever seen a mango dipped in cheese? Well, that's your what your baby looks like this week due to a little growth spurt (its about a half pound in weight and six inches long) and a substance called vernix caseosa. This greasy white stuff covers your baby's skin, protecting it from the surrounding amniotic fluid. (Without it, it would look totally wrinkled as it entered the world.) http://www.whattoexpect.com/pregnancy/week-by-week/week-19.aspx

    Now you can see if your baby is a boy or a is a girl. if it is a girl her uterus is now fully formed and her ovaries are holding about seven million primitive eggs. if it is a boy his testicles have begun their descent from the abdomen to their ultimate destination — the scrotum. Ethier way the baby is growing.

    your babynow weighs a full two pounds and measures nine-plus inches. And this week eyes, which until now were developing under fused eyelids, start to open. Of course, there's not much to see in there, but if your baby spots a bright light (or hears a loud noise) near your belly, you may notice an increase in fetal activity. Her brain is more developed and sophisticated. http://www.whattoexpect.com/pregnancy/week-by-week/week-26.aspx

    week 30
    your baby is getting bigger every day, weighing in at over three pounds now . Also growing daily is his brain, which is actually starting to look like the real thing with those characteristic grooves and wrinkles. And now that your little genius can regulate his own body temperature and turn up the heat, he'll start shedding lanugo, the downy body hair that's been keeping him warm up until now. http://www.whattoexpect.com/pregnancy/week-by-week/week-30.aspx#
  • week 34

    Your baby is clocking in at five pounds and could be as tall as 20 inches by now, and the vernix (the white coating protecting your baby’s skin) is getting thicker. This week, a boy's testicles start making their way down from his abdomen to their final destination: his scrotum . While about three to four percent of boys are born with undescended testicles but it will grow eventually. finger nails grow too. http://www.whattoexpect.com/pregnancy/week-by-week/week-34.aspx
  • week 39

    Coming down to the wire, your baby weighs around seven to eight pounds and measures 19 to 21 inches. Those measurements won't change much from now on, but her brain is still growing at an astonishing rate, a pace that will continue for the first three years of life. Her pink skin has now turned whitish (even babies who'll eventually have darker skin appear whitish now — they haven't yet developed pigment).http://www.whattoexpect.com/pregnancy/week-by-week/week-39.aspx
