By now, I weigh 3.75 pounds (pick up a large jicama) and am about 16.7 inches long, taking up a lot of space in mommies uterus. She's gaining about a pound a week and roughly half of that goes right to me. In fact, I'll gain a third to half of my birth weight during the next 7 weeks as I fatten up for survival outside the womb. I now have toenails, fingernails, and real hair (or at least respectable peach fuzz). My skin is becoming soft and smooth as I plump up in preparation for birth.
