19 Weeks!

How your baby's growing:
Your baby's sensory development is exploding! His brain is designating specialized areas for smell, taste, hearing, vision, and touch. Some research suggests that he may be able to hear your voice now, so don't be shy about reading aloud, talking to him, or singing a happy tune if the mood strikes you.

Your baby weighs about 8 1/2 ounces and measures 6 inches, head to bottom — about the size of a large heirloom tomato. (***OK, Time out! The doctor said 10 ounces at 18 weeks was normal! Looks like Cancan is an overachiever just like his mama and daddy... and he likes to eat, too!)

His arms and legs are in the right proportions to each other and the rest of his body now. His kidneys continue to make urine and the hair on his scalp is sprouting. A waxy protective coating called the vernix caseosa is forming on his skin to prevent it from pickling in the amniotic fluid. (Pickling... we'll have none of that, I tell you. Talk about gross!)

How your life's changing:
Think you're big now? You'll start growing even faster in the weeks to come. (Oh, great...) As a result, you may notice some achiness in your lower abdomen or even an occasional brief, stabbing pain on one or both sides — especially when you shift position or at the end of an active day. Most likely, this is round ligament pain. The ligaments that support your uterus are stretching to accommodate its increasing weight. This is nothing to be alarmed about, but call your practitioner if the pain continues even when you're resting or becomes severe.

You may be noticing some skin changes, too. Are the palms of your hands red? (Nope, not yet...) Nothing to worry about — it's from the extra estrogen. You may also have patches of darkened skin caused by a temporary increase in pigment. When these darker patches appear on your upper lip, cheeks, and forehead, they're called chloasma, or the "mask of pregnancy." (Yippee! Red palms and dark patches! Just what I wanted for Christmas! haha)
