More positive news regarding antidepressants are described in Nursing Kids on Prozac via U.S. News:

Babies with depressed moms tend to weigh less after six months than babies with happy moms; less weight often means more illness. But the same study that uncovered this disturbing fact has also turned up hope: Breast-fed babies grow better if depressed moms take drugs that alleviate depression. This challenges a popular belief that the traces of Prozac, Paxil, and similar drugs that seep into breast milk can harm a nursing infant.

“Time and again, doctors are telling nursing women that if they’re depressed, they can’t take medicine,” says Victoria Hendrick, a psychiatrist at the University of California-Los Angeles and an author of the study. That may be true during pregnancy. Other research found that pregnant women who took Paxil during their third trimester were more likely to have infants with medical complications than were mothers who took other kinds of drugs. Yet few studies have looked at how Paxil-like antidepressants, known as selective serotonin reuptake inhibitors (SSRIs), affect life after the womb.

So Hendrick followed a group of nursing babies and their mothers for six months. Infants with depressed moms who improved on SSRIs grew just as well as did infants with mentally healthy moms. Both groups grew bigger than babies whose moms remained depressed, even if they took medicine. “We were struck by the results,” Hendrick says. “It didn’t seem like exposure to antidepressants had any bad effect on the baby’s weight.” Hendrick’s study, published earlier this year in the Journal of Clinical Psychiatry, also found that babies whose mothers had major depressive episodes that lasted at least two months weighed less than babies whose moms were depressed only mildly or for shorter periods.
