Good news for parents of kids with nut allergies. Lucy’s gluten-free cookies, made with milk, eggs, tree nuts, gluten, are now available at Starbucks. I met up with “Dr. Lucy” last week and she was telling me that the hardest thing about having a child with allergies is figuring out what to take on the road. “My line is all about convenience,” she said. It’s also about deliciousness — my kids couldn’t tell the difference between these chocolate chips and their tried-and-trues.
