Do a good deed and donate diapers on Monday for local, low-income families.

The third annual Cobb Diaper Day collection will benefit several area non-profit organizations, including MUST Ministries, Sweetwater Valley CAMP and The Center for Family Resources.

More than 120,000 diapers have been donated to local families over the past two years. The diapers will be collected at 5 p.m. at Glover Park in the Marietta Square.
