Mom, your body still provides the majority of nutrients for your baby, yet
the fetus' blood supply is becoming more involved in this process. The jaw
bone is hardening, and tooth buds are growing. Vocal cords are growing as
well.
Your baby is about two and a half inches long and weighs approximately a
third of an ounce. Since your baby's bones are rapidly forming, it is
important for you to be getting enough calcium in your diet. Both sexes
are forming genitals, yet they are indistinguishable until about 14 weeks.
