Your Baby

Your baby weighs in between a half to one pound this week and is 10 inches long from crown to rump. A creamy, protective coating called vernix caseosa, which is secreted by her glands, coats her skin, protecting it from the amniotic fluid. She's practicing for her first breath outside the womb, moving her chest up and down as if she were breathing through the nose. Her genitals are fully formed.

Your Body

Congratulations--you're halfway there! At this stage, your oval-shaped uterus is nearly level with your belly button and grows a centimeter each week. If you're scheduled for a checkup, your doctor or midwife may no longer need to use a Doppler to hear your baby's heartbeat; the sound is loud enough that a regular stethoscope can easily do the job.

Do's and Don'ts

Do splurge on the occasional salon manicure when you feel the need for pampering. Pregnancy can cause your nails to grow faster, making it a hassle to keep up with constant retouching. Choose lighter, more natural hues that won't show chipping or opt for low-maintenance nails, shaping them with a file and polishing them with a buffer. 

Health

Lactose intolerant? Instead of foregoing milk altogether, try calcium- and vitamin D- enriched rice or soy milk. Cheese is also a good source of calcium, which your baby needs to form strong teeth and bones; it doesn't have as much lactose as regular milk and may be easier to digest. Yogurt is another good choice.
