How your baby's growing:

  • This week's big developments: Your baby can now squint, frown, grimace, pee, and possibly suck his thumb! Thanks to brain impulses, his facial muscles are getting a workout as his tiny features form one expression after another.
  • His kidneys are producing urine, which he releases into the amniotic fluid around him a process he'll keep up until birth.
  • He can grasp, too, and if you're having an ultrasound now, you may even catch him sucking his thumb.
  • In other news: Your baby's stretching out. From head to bottom, he measures 3 1/2 inches about the size of a lemon and he weighs 1 1/2 ounces.
  • His body's growing faster than his head, which now sits upon a more distinct neck.
  • By the end of this week, his arms will have grown to a length that's in proportion to the rest of his body. (His legs still have some lengthening to do.)
  • He's starting to develop an ultra-fine, downy covering of hair, called lanugo, all over his body.
  • Your baby's liver starts making bile this week a sign that it's doing its job right and his spleen starts helping in the production of red blood cells.
  • Though you can't feel his tiny punches and kicks yet, your little pugilist's hands and feet (which now measure about 1/2 inch long) are more flexible and active.

Note: Every baby develops a little differently even in the womb. Our information is designed to give you a general idea of your baby's development.
How your life's changing:

  • Welcome to your second trimester! Your energy is likely returning, your breasts may be feeling less tender, and your queasiness may have completely abated by now.
  • If not, hang on chances are good it will soon be behind you (although an unlucky few will still feel nauseated months from now).
  • The top of your uterus is a bit above your pubic bone, which may be enough to push your tummy out a tad. Starting to show can be quite a thrill, giving you and your partner visible evidence of the baby you've been waiting for.
  • Take some time to plan, daydream, and enjoy this amazing time. It's normal to worry a bit now and then, but try to focus on taking care of yourself and your baby, and having faith that you're well equipped for what's ahead
