We were interested in how fathers felt about their babies, how they felt about themselves as parents, and how they (and their spouses) felt about the fathers in other adult roles. Fathers developed an intense attachment to their babies and a sense of themselves as primary caregivers in stages.

A prism is a polyhedron for which the top and bottom faces (known as the bases) are congruent polygons, and all other faces (known as the lateral faces) are rectangles. (Technically, when the sides are rectangles, the shape is known as a right prism, indicating that the lateral faces meet the sides of the base at right angles. In this lesson, when we use the term prism, we mean a right prism. But there are other types of prisms, too.) A prism is described by the shape of its base. For instance, a rectangular prism has bases that are rectangles, and a pentagonal prism has bases that are pentagons.
