Catherine Poulos, left, and Hannah Gould sing Christmas carols together. The children are members of the four and five's class at St. Elizabeth Ann Seton Preschool in Baldwinsville, which participates in an intergenerational program. Once a month, they get together with the senior "Lunch Bunch" group in the church, and share activities such as singing, exercising and making crafts. The four and five's class is a unique, small class for children with fall birthdays who need an extra year before attending kindergarten and children who just miss the cut-off date for kindergarten. To register for this class or the three and four-year-old classes, call Karen Gell at 652-9364.
