I can’t help but whine about this. If you are making an exceptionally snotty, judgemental statement about someone’s “level of education,” please make sure you check your spelling. I get typos, but when you spell (for example) ”equal” as “eikuwal”, that is not a typo. How can anyone take someone discussing education seriously when they can’t even spell very simple words correctly?

Hey pot, meet kettle. You two have a lot in common.

Head to bottom, your baby is approximately 5 1/2 inches long (about the length of a large sweet potato) and she weighs almost 7 ounces. She’s busy flexing her arms and legs — movements that you’ll likely start noticing more and more. Her blood vessels are visible through her thin skin and her ears are now in position and stand out from her head. Myelin (a protective covering) is beginning to form around her nerves, a process that will continue for a year after she’s born. If you’re having a girl, her uterus and Fallopian tubes are formed and in place. If your baby is a boy, his genitals are noticeable, though he may hide them from you during an ultrasound.

Your baby weighs about 5 ounces now, and he’s around 5 inches long — about the size of a large onion. He can move his joints, and his skeleton — until now rubbery cartilage — is starting to harden to bone. His sense of hearing is also developing. The umbilical cord, his lifeline to the placenta, is growing stronger and thicker.

At 4 1/2 inches long (head to bottom) and 3 1/2 ounces, your baby is about the size of an avocado. In the next three weeks, she’ll go through a tremendous growth spurt, though, doubling her weight and adding inches to her length. Her lower limbs are much more developed now. Her head is more erect than it has been, and her eyes have moved toward the front of her head. Your baby’s ears are close to their final position, too. Some of her more advanced body systems are working, including her circulatory system and urinary tract. Her heart is now pumping about 25 quarts of blood each day, circulating her total blood volume through her body many times. (By the end of your pregnancy, this will increase to about 190 quarts.) The patterning of her scalp has begun, though her hair isn’t recognizable yet. Although closed, her eyes are moving (slowly), and she’s even started growing toenails.

At around 4 inches long, crown to rump, your baby now weighs about 2 1/2 ounces. He’s busy inhaling and exhaling amniotic fluid, which will help develop the air sacs in his lungs. His legs are growing longer than his arms now, and he can move all his joints and limbs. That means his hands are more functional, too. Sweat glands are appearing, and although his eyelids are fused shut, he can sense light. If you shine a flashlight at your tummy, he’s likely to move away from the beam. There’s not much for your baby to taste at this point, but his 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 sex 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.)
