"All these women can think of is to avoid trouble with their partners or with their parents. Some women have greater fear of losing their partners than losing their child. They usually hide the pregnancy until it is too late, and when the baby arrives, they panic and the only thing they can think of is how to get rid of it," German author Annegret Wiese wrote in her book "When Mothers Kill."
Professor Anke Rohde, a psychiatrist at the Medical University Clinic in Bonn, said the baby drops were no cure-all.
"This may be one way to deal with the problem, but certainly can't be the only way," she told ABCNEWS.com. "Mothers caught in such a horrific situation are completely stressed out. They can't even think straight. The risk is that because of that stressful situation they'll ignore or simply overlook the possibility to drop off their babies. More needs to be done in order to help those women."
Italy has had a law in place since 1975 that also guarantees women in the country illegally won't be deported if they decide on such an anonymous birth.
The northern Italian town of Padua installed a baby drop to curb incidents of babies dumped in the trash and public places. The National Association for Adoptive and Foster Families says that 400 newborns are abandoned in Italy every year -- a 10 percent yearly increase.
