Jack was very affectionate, almost never cried or fussed, and always seemed curious about the faces that appeared above his crib, even those of strangers. Wilbur, on the other hand, was irritable from the outset, often cried for no apparent reason, and usually
became upset when strangers' faces came into view. Thus, the Williamses wondered about their children's early personalities and about children in general.
