11-week baby

The baby is completely formed even though he fits snugly into the doctor's hand. The ears were first distinguishable during the sixth week; the inner ear is completely formed in mid-pregnancy.

The baby is held in the hand of the late Professor Sir Albert William Liley, the pioneer of medical treatment for children in the womb. He has been called the father of foetology for his work, including the first successful blood transfusion on an unborn child (at around seven months' gestation) in 1963.

Liley commented: "This situation highlights the fact that, in modern antenatal care, we are concerned with the welfare of two patients: the mother and the child." (The Tiniest Humans, edited by R L Sassone, 1977, p.6.)
