Kate Middleton and her husband, Prince William, were gifted with Finnish baby box by Finland´s Social Security Service in 2013
The Maternity package (Finnish: Äitiyspakkaus) is a kit granted by the Finnish social security institution Kela, to all expectant or adoptive parents who live in Finland or are covered by the Finnish social security system. The package contains children's clothes and other necessary items, such as nappies, bedding, cloth, gauze towels and child-care products. It was first issued in 1938 to parents with a low income, and contained a blanket, crib sheets, diapers, and fabric which parents could use to make clothing for the baby.
Since 1949 it has been given to all mothers-to-be, provided they visited a doctor or municipal pre-natal clinic before their fourth month of pregnancy, and the pregnancy has lasted at least 154 days. The contents of the package are updated approximately every year.
