Legislation may mandate staffing ratios (for example, 6 weeks to 12 months, 1:4; 12 months to 18 months, 1:5; 18 months to 24 months, 1:9; etc.). The caregiver-to-child ratio is one factor indicative of quality of care. Ratios vary greatly by location and by daycare center. Potential consequences of a caregiver:child ratio which is too high could be very serious. However, many states allow a higher numbers of toddlers to caregivers and some centers do not comply consistently. For example, within the US: Pennsylvania, ages 1–3, 1 teacher to 5 children; Missouri: age 2, 1 teacher to 8 children; North Carolina: 1 teacher to 10 children.
In Denmark day-cares accept children ranging from 6 months old to 3 years old. 91.2% of 1-2 year old children are enrolled in different types of day-care institutions. Most of these are managed by a municipality and mostly government funded. The different types of institutions ranges from separate day-care institutions (Vuggestue), kindergartens with a day-care department (Integrerede institutioner) and in-home day-care (Dagpleje). http://y2u.be/eeCahRCgOfI
