How Our Baby Is Growing

(Accoring to BabyCenter.com)
At around 4 inches long, crown to rump, your baby now weighs about 2 1/2 ounces. He/She is busy inhaling and exhaling amniotic fluid, which will help develop the air sacs in his/her lungs. His/Her legs are growing longer than his/her arms now, and he/she can move all his/her joints and limbs. That means his/her hands are more functional, too. Sweat glands are appearing, and although his/her eyelids are fused shut, he/she can sense light. If you shine a flashlight at your tummy, he/she is likely to move away from the beam. There's not much for your baby to taste at this point, but his/her taste buds are beginning to form. And if you have an ultrasound, you may be able to find out whether your baby's a boy or girl! (Don't be disappointed if it remains a mystery, though. Nailing down the gender depends somewhat on how clear the picture is and the position of your baby during the ultrasound; he may be curled or turned in such a way as to keep you in suspense.)
