New Canaan’s Shawnee Knight and Tina Kramer had been packing food for needy Stamford kids for some six months before they had a chance to meet, in person, the children and teens they’d been helping. The moment came during a special Christmas delivery. Knight and Kramer the summer prior had developed their model of giving under the national Blessings in a Backpack program. At Christmas, the pair arranged to deliver, themselves, special holiday backpacks for the 100 kids they served at Stamford’s Domus—kids on free or reduced lunch at a school that serves some of the city’s most at-risk youth. In those backpacks—themselves new and donated—the kids found not just food but also socks, ear buds, candy, nail polish and shampoo for the girls, Skittles, shampoo and conditioner, pancake mix and syrup.
