Hello again everyone.
As my readers well know, the Old Lady and I are grandparents. Our little grandchild is in his/her first trimester in Annie’s tummy (well, not exactly her tummy, but there is no need to be technically correct here).
What does that mean? Its early, like the first three innings of a baseball game, but things are happening. What kind of things? I sure don’t know, but there are experts who publish stuff on the internet who do know. So, what better way to edumecate myself that to do some googling and share it with you. I found this on the “What to Expect” website.
BABY’S GROWTH DURING FIRST TRIMESTER
During the first trimester alone your baby changes from a single fertilized cell (a zygote), to the embryo that implants itself in your uterine wall, to a peach-sized bundle of growing limbs and body systems. Organs take shape, and baby starts to move. Here are a few of the big highlights happening in this exciting time:
- Baby’s bones: By about week 6, baby starts to sprout arms, legs, hands and feet — and fingers and toes around week 10.
- Hair and nails: Skin begins forming between weeks 5 and 8, with hair follicles and nail beds forming around week 8.
- Digestive system: By about week 8, baby’s intestines will begin forming, and your baby will have already gone through two sets of kidneys (with the third and final set on its way!).
- Sense of touch: Your baby will have touch receptors on his face (mostly lips and nose) around week 8. By week 12, he’ll have receptors on his genitals, palms and the soles of his feet.
- Eyesight: Optic nerves (which pass info from the eyes to the brain and back) and lenses begin to form by week 4, with the retina beginning to form around week 8.
- Heart: By week 5, the tube that will become your baby’s heart begins to beat spontaneously. It will become stronger and more regular — and you’ll be able to hear it! — around week 9 or 10 (though sometimes later, depending on your baby’s position in your uterus).
- Brain: By about week 8 of pregnancy, your baby’s brain will be wiggling his developing limbs.
- Sense of taste: Your baby will have developed taste buds that connect to his brain by about week 8 — but he’ll need taste pores before he can taste the surrounding amniotic fluid (which, by the way, tastes like your most recent meal).
Other major first-trimester milestones include the formation of muscles, the production of white blood cells to fight off germs and the development of vocal cords.
Quite interesting, eh?
Thanks for reading and stay tuned.
