Összhang Közhasznú Egyesület is an independent, non-religious and non-political nonprofit organization based in Eger, Hungary. It supports expectant parents, mothers, young children and families through the perinatal period, with the aim of promoting a more respectful experience of childbirth, birth and breastfeeding, and fostering early bonds between mothers and children. Its activities span preparation for pregnancy and birth, support during pregnancy and after delivery, and community programs for families with babies and young children.

Offerings include prenatal preparation sessions, workshops, pregnancy yoga, clubs, talks and rhyme-time activities, alongside individual consultations and other support services. The association also provides a directory of perinatal professionals in Heves County, covering services from pregnancy planning until a child is two years old or beyond, and shares practical information through a free email series. Most programs take place at its Eger premises, with some events held elsewhere.

Many activities are free for members, while workshops may be self-funded. Families can support the organization through membership or a personal income tax donation
