19 Weeks...

Your babies each weigh approximately 8 ounces and are about 6 inches from crown to rump. The exterior layers of skin tissue are developing to form your babies' one-of-a-kind fingerprints. Even though identical twins (or triplets or quads) may have the same blood type and look exactly alike, they each have unique fingerprints. The amniotic fluid that surrounds your babies allows them to freely move their arms and legs and is also sometimes swallowed to practice digestion.
