Oh how time gets away from you in the holiday season!
Week 19: Your baby's sensory development is exploding! Her brain is designating specialized areas for smell, taste, hearing, vision, and touch. Some research suggests that she may be able to hear your voice now, so don't be shy about reading aloud, talking to her, 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. Her arms and legs are in the right proportions to each other and the rest of her body now. Her kidneys continue to make urine and the hair on her scalp is sprouting. A waxy protective coating called the vernix caseosa is forming on her skin to prevent it from pickling in the amniotic fluid
Week 20: Your baby weighs about 10 1/2 ounces now. He's also around 6 1/2 inches long from head to bottom and about 10 inches from head to heel — the length of a banana. (For the first 20 weeks, when a baby's legs are curled up against his torso and hard to measure, measurements are taken from the top of his head to his bottom — the "crown to rump" measurement. After 20 weeks, he's measured from head to toe.)He's swallowing more these days, which is good practice for his digestive system. He's also producing meconium, a black, sticky by-product of digestion. This gooey substance will accumulate in his bowels, and you'll see it in his first soiled diaper (some babies pass meconium in the womb or during delivery).
Week 21: Your baby now weighs about three-quarters of a pound and is approximately 10 1/2 inches long — the length of a carrot. You may soon feel like she's practicing martial arts as her initial fluttering movements turn into full-fledged kicks and nudges. You may also discover a pattern to her activity as you get to know her better. In other developments, your baby's eyebrows and lids are present now, and if you're having a girl, her vagina has begun to form as well.
Week 22: At 11 inches (the length of a spaghetti squash) and almost 1 pound, your baby is starting to look like a miniature newborn. His lips, eyelids, and eyebrows are becoming more distinct, and he's even developing tiny tooth buds beneath his gums. His eyes have formed, but his irises (the colored part of the eye) still lack pigment. If you could see inside your womb, you'd be able to spot the fine hair (lanugo) that covers his body and the deep wrinkles on his skin, which he'll sport until he adds a padding of fat to fill them in. Inside his belly, his pancreas — essential for the production of some important hormones — is developing steadily.
Week 23: Turn on the radio and sway to the music. With her sense of movement well developed by now, your baby can feel you dance. And now that she's more than 11 inches long and weighs just over a pound (about as much as a large mango), you may be able to see her squirm underneath your clothes. Blood vessels in her lungs are developing to prepare for breathing, and the sounds that your baby's increasingly keen ears pick up are preparing her for entry into the outside world. Loud noises that become familiar now — such as your dog barking or the roar of the vacuum cleaner — probably won't faze her when she hears them outside the womb.
That's the update for now!! I cannot believe that I'm only a few weeks from being in my third trimester!
