BOSTON (AP) — Massachusetts officials are stepping up efforts to reduce sudden infant death syndrome.

Throughout October, a public awareness campaign will focus on educating parents and caregivers about how to make sure infants are sleeping in a safe manner.

Experts recommend that babies be put to sleep on their backs, and that they be alone in their cribs without pillows, quilts or other soft surfaces. Parents should never share their own beds with infants.

The campaign will include the new web page Mass.gov/SafeSleep and public service posters on MBTA trains.

All the state's maternity hospitals also plan to give new parents a copy of the book "Sleep Baby, Safe and Snug" during the month.

Officials say sudden infant death syndrome affects about 30 to 50 families each year in Massachusetts.
