Family child care homes can be operated by a single individual out of their home. In most states, the legal age of 18 is only required. There may be occasions when more than one individual cares for children in a family childcare home. This can be a stay-at-home parent who seeks supplemental income while caring for their own child. There are also many family childcare providers who have chosen this field as a profession. Both state and county agency legislation regulate the ratios (number and ages of children) allowed per family child care home. Some counties have more stringent quality standards that require licensing for family child care homes while other counties require little or no regulations for childcare in individuals' homes. Some family child care homes operate illegally with respect to tax legislation where the care provider does not report fees as income and the parent does not receive a receipt to qualify for childcare tax deductions. However, licensing a family child care home is beneficial for family child care home providers so that they can have access to financial benefits from their state government, or the federal government where they are allowed to accept children from parents who meet the criterion to benefit from the government childcare subsidy funding. Examples of such benefits are: free Professional Development and training courses, Child And Adult Care Food Program (which allows eligible childcare and family childcare home providers to claim a portion of costs relating to nutritious meals served to children), and more;.
Due to social pressure, parents of sick children in childcare may be willing to give unnecessary medical care to their children when advised to do so by childcare workers and even if it is against the advice of health care providers. In particular, children in childcare are more likely to take antibiotics than children outside of childcare.
Spain provides paid maternity leave of 16 weeks with 30-50% of mothers returning to work (most full-time) after this, thus babies 4 months of age tend to be placed in daycare centers. Adult-infant ratios are about 1:7-8 first year and 1:16-18 second year. Public preschool education is provided for most children aged 3–5 years in "Infantil" schools which also provide primary school education.
