In seeming acceptance of the new view of mommies, daddies are seen here not only driving steamrollers or taxis or police cars, pulling teeth or presiding over big offices, but also doing ""what Mommy does"" -- changing diapers, cooking dinner and bathing the children. Don't fear for the traditional roles though, for Daddy is obviously just helping out; he's still pictured coming home from work with a bright bunch of flowers for a beaming, aproned, waiting Mommy. And though Stewart and Madden with bland impartiality paint their daddies in all skin and collar colors, it seems to be by their catalogued possessions -- ties and trousers, wallets, checkbooks and keys, lawn mowers, tape recorders and tools -- that they are identified as daddies. Inevitably the closing common trait is a positive one: ""Sometimes daddies get angry. . . . But all daddies love their little boys and girls no matter what."" And if you can find the composite child this desultory Daddy has begotten, he might be comforted.
