"This Child Is Mine," which has to be one of the most insipid movie titles ever conceived--at least the most insipid since last week's "A Time to Live"--takes on the problem of the rights of adoptive parents versus the rights of what used to be called the "natural" mother but, apparently because of the pejorative implications, is now being buzz-worded as the "birth" mother.

In this case, it is Lindsay Wagner playing a career woman--"Miss Trendy around town," her husband (Chris Sarandon) calls her--who would give a bionic right arm to have a baby. Tenaciously (and disgustingly) upscale, the couple --she is in merchandising, he in architecture--have tried everything from reconstructive surgery to artificial insemination.

"Your chances of having a baby are pretty slim," says their doctor, adding that they might try other options such as in vitro fertilization or adoption. "I'm not morally against having a test-tube baby," Miss Trendy tells her husband later. "It's just so experimental. . . . And to get involved with a surrogate mother. . . . Doesn't that strike you as bizarre?"
