而且小V繼上週的快速成長 尤其體重以四倍成長的速度進行這時期會感覺到胎動 可以明顯分辨小V是醒著還是睡著狀態
小V開始練習呼吸這個動作了 雖然肺部還未發育完全 無法在母體之外呼吸
信中告訴懷著女寶寶的媽媽們 在20週這個時期 可以開始準備當外婆了
(哈哈哈 看到這我大笑出來呢 女兒都還沒出生 就要媽媽們準備可以當外婆)
(目前我是還好 只會覺得走路不能走太快 不然會喘而已)
Week 20 - Second Trimester
Your Week By Week
Over the last four weeks, your baby has grown an incredible amount, and has just about quadrupled his weight. He's big enough that you should be feeling fluttering or quickening quite regularly now. In fact, from his movements you may be able to tell if your baby is awake or asleep. Your baby is anywhere from 25 - 28 cm or 10 inches long and weighs 285-300 grams or 10-11 ounces.
Your baby has started to practice breathing motions, even though his lungs are not yet mature enough to breathe enough air to allow him to survive outside your body. Lanugo (the fine hair) covers your baby's whole body, and hair on his scalp is beginning to grow. Your baby's ears are fully functional now and he enjoys the sound of uterine noise. All the organs and structures of your baby's body are formed and your baby is now entering a period of simple growth. And you may be getting ready to be a grandma already: if your baby is a girl, her uterus is beginning to develop!

Congratulations -- you are halfway through your pregnancy!
As the baby and uterus grow, some moms report a little trouble breathing, or taking deep breaths, as their lungs become cramped with the internal organs. While not a serious complication, it can be uncomfortable. Once your baby drops or engages into the pelvis (which happens about four to six weeks before your due date) this will be relieved.If you haven't yet, you might want to start coming up with some of your favorite baby names. It might help to look through family history for ideas or pay attention to names when you watch movies or read books. Don't forget: when thinking about a baby name, be sure to pay attention to the initials your baby will have. You wouldn't want to try to personalize something for your baby, only to realize that your baby's initials spell -- or sound like -- something you all won't be happy about down the road. (Think TOE, CRP, COW, HOR, GAG, BRF).
