How your baby's growing: By this week, your baby weighs two and a quarter pounds (like a Chinese cabbage) and measures 14.8 inches from the top of his head to his heels. He can blink his eyes, which now sport lashes. With his eyesight developing, he may be able to see the light that filters in through your womb. He's also developing billions of neurons in his brain and adding more body fat in preparation for life in the outside world.
