This also contributes to self-selection of female workers in the low-paid public sector rather than the better paid part of the informal sector (Chapter 1). Federal Law stipulates that parents should not pay more than 20% of the cost of childcare (this is 10% for parents with at least three children, and care is free for handicapped children), and sets rules on compensation towards parental fees (20% for the first child, 50% for the second and 70% for the third). Many regions aim to provide free childcare to low-income families. However, the system is under some pressure as regions which are responsible for its financing are struggling to meet the cost, including for parental fee support.
