Our baby's development 20-22 weeks

20 weeks
Your baby weighs about 10 1/2 ounces now. She's also around 6 1/2 inches long from head to bottom, and about 10 inches from head to heel. (For the first 20 weeks, we use measurements taken from the top of the baby's head to her bottom — known as the "crown to rump" measurement. After that, we use measurements from head to toe. This is because a baby's legs are curled up against her torso during the first half of pregnancy and are very hard to measure.)

A greasy white substance called vernix caseosa coats her entire body to protect her skin during its long submersion in amniotic fluid. (This slick coating also eases the journey down the birth canal.) Your baby is swallowing more, which is good practice for her digestive system. She's also producing meconium, a black, sticky substance that's the result of cell loss, digestive secretion, and swallowed amniotic fluid. This meconium will accumulate in her bowels, and you'll see it in her first messy diaper (although a few babies pass it in utero or during delivery).

21 weeks
Your baby now weighs about three-quarters of a pound and is approximately 10 1/2 inches long. His eyebrows and eyelids are fully developed. And you can certainly feel him move. He's oblivious to your schedule, though, so don't be surprised if he starts working out just when you're settling down for the night.

Yes, I can certainly feel the baby moving! Pretty much anytime I eat, lie down, relax or sit - I get some punching from the inside! It is very exciting though, and now if I lie down with my tummy exposed, I can see my tummy shaking where I am being kicked.

22 weeks
Your baby now looks like a miniature newborn, checking in at 10.9 inches and almost 1 pound. Her skin will continue to appear wrinkled until she gains enough weight to fill it out, and the fine hair (lanugo) that covers her head and body is now visible. Her lips are becoming more distinct, and the first signs of teeth are appearing as buds beneath her gum line. Her eyes are developed, though the iris (the colored part of the eye) still lacks pigment. Eyelids and eyebrows are in place, and her pancreas, essential for hormone production, is developing steadily.

I'm enjoying being pregnant, but I also can't wait until we can meet our baby. I guess 4 months isn't too long to wait... My tummy is pretty big now so hardly any clothes fit. I went on a giant shopping spree today to buy new clothes so I actually have something to wear! And tonight I start aquarobics for pregnant people. I hope it's fun. I even bought a swimsuit especially (I doubt I would be able to squeeze into my old ones).
