By the end of Week 10, your baby graduates from embryo to fetus, which literally means "little one." It also translates to "I'm just going to keep getting bigger and bigger and so are you!" Other highlights this week:
- Your baby has finally morphed from a little tadpole into, well, a baby. Not only is the face more human-like, but that unflattering "tail" (really just the developing spinal cord) has disappeared, fusing into the spinal column.
- Your baby now has discernible fingers and toes, which will explain the steady stream of kicks and punches you'll feel down the line.
- Junior's skeleton is starting to grow and harden. The ears are beginning to take shape and the eyelids are no longer transparent. Tooth buds are forming, although your baby won't get any teeth until six or seven (or eight or nine or 10) months after birth.
- Baby's brain will make an incredible 25,000 new neurons every minute this week. While you may feel like you're losing as many as he's gaining, we can assure you it's not permanent. "Pregnancy brain," like nausea and bloating, is a temporary symptom that soon shall pass. (And then you'll get "Mommy brain," but we won't go there now.)
- If you're baby is a boy, he's started producing that macho hormone testosterone. And whether your baby is a boy or a girl, the kidneys are creating copious amounts of urine. Lucky for you, you won't have to change a diaper for another 30 weeks.
- Baby weighs only 4 grams and measures 1 1/2 inches, about the size of a mondo Brazil nut.
