She weighed six pounds seven and one-half ounces at birth, normal enough infant statistics for a child of small parents - a father five foot eight and a mother five foot five. indeed, she seemed at birth normal in all other respects as well. T.Z. was born into a family of two older brothers and a third child who had died young.
