The Twins Association is an interest organization founded in 1984, which is aimed at anyone caring for twins and multiples, including triplets and quadruplets. The organization has specific expertise on topics related to twins and multiples, and works to promote their interests. One of the most important measures has been the work for extended parental leave for parents of twins, which was introduced in 2018.
The association organizes various courses, including twin birth preparation courses and themed courses, which provide information and support to parents and guardians. In addition, the Twins Association offers membership benefits and guidance, and acts as a nationwide competence center on multiples. The organization also has a podcast that deals with relevant topics for twin and multiple families.
