British Royal Couple Given Finnish Baby Box A future British king or queen might spend some early hours sleeping in a cardboard box - if a maternity package donated by Finland's social security service proves a success. The Nordic country has given a baby box to Prince William and former Catherine Middleton, who are expecting their first baby in mid-July. The brightly colored cardboard box doubles as a cot, complete with mattress and sheets, and contains numerous baby items including a sleeping bag, jump suits, socks, pants, hats, bonnets and diapers. Maternity packages have been given to expectant mothers in Finland since 1938. A spokesperson for the royal couple at Kensington Palace said Wednesday that the Duke and Duchess of Cambridge were "delighted" by their baby box, and that "it was a very thoughtful gesture and we're very grateful for it."
