Baby's the size of a naval orange!

Continuing the march towards normal proportions, baby's legs now outmeasure the arms. And, finally, all four limbs have functional joints. Our fetus is squirming and wiggling like crazy down in the womb, though I still can't feel the movements.

Also, although baby's eyelids are still fused shut, it can sense light. If we shine a flashlight at my tummy, for instance, baby's likely to move away from the beam. [Though I can't feel that yet.] There's not much for our baby to taste at this point, but it is forming taste buds. Finally, if we were to have an ultrasound this week, we may be able to find out whether our baby's a boy or a girl! [But we aren't scheduled to have an ultrasound for at least another month.]
