PITTSBURGH, Pa.—Offering plain-language answers and reminders to help Pittsburgh mothers plan for healthy pregnancies, childbirth, and babies, three new booklets from AAAS and The Heinz Endowments were released Saturday during a free public health fair. The booklets are one part of a larger strategy by The Heinz Endowments to support healthier families by working to reduce the rate of babies born too small as well as the number of infants who die before their first birthdays.
