BabySafeHaven is a Web site launched today by Massachusetts officials as part of a campaign to make the public aware of a new state law that allows a parent anonymously to leave a newborn who is less than a week old at a hospital, police station or manned fire station without legal consequences. The awareness campaign also includes posters on public transit, two billboards and a statewide safe haven hotline, 1-866-814-SAFE. The law took effect Oct. 29, 2004.
