Shyer and Meyers... are endlessly inventive. They're not afraid to be sophisticated and screwballish in the best '30s tradition, and they know just how far to exaggerate for laughs without leaving touch with reality entirely or destroying sentiment. The humor in Baby Boom is sharp without being heartless.

Baby Boom makes no effort to show us real life. It is a fantasy about mothers and babies and sweetness and love, with just enough wicked comedy to give it an edge.

One of the most important things about Baby Boom, aside from being amusing all the way through, is that Diane Keaton gets her first chance to carry a comedy all by herself. [28 Oct 1987, p.E06]

Keaton is funny when she's tough, and funny when she's soft; the Baby Boom combination, for all the film's calculations and shameless cooing (the baby's dubbed, for pity's sake), is quite appealing. [7 Oct 1987, p.D8]

Baby Boom isn't much more than a glorified sitcom, but it's funny, and it's liable to hit home. The reason: a devilishly good performance by Diane Keaton.
