Content: The limb buds are now clearly arms and legs, while the fingers and toes are still developing. Baby’s Development at 12 Weeks
At 12 weeks, the fetus has grown to about 2 inches (4.4cm) in length and may begin to move by itself. The fingers and toes are discernible, and the fetal heartbeat may be audible by Doppler ultrasound. The developing sex organs may be identified by ultrasound techniques. Baby's Development at 16 Weeks
At 16 weeks, the fetus is about 4 and one-half inches long and resembles an infant; the eyes blink, the heartbeat is easier to locate, facial features (nose, mouth, chin and ears) are distinct, and the fingers and toes are clearly developed; the skin on the fingers and toes even has distinct patterns (fingerprints!). Women should be able to feel the uterus at about 3 inches (6.6 cm) below the belly button; this is the beginning of the "baby bump" (abdominal swelling due to an expanding uterus) in some women. Baby's Development at 20 Weeks
At 20 weeks, the developing fetus is about 6 inches long (13.2 cm) and may weigh about 10 ounces.
