There are three main types of day care: center-based care, family day care, and informal care arrangements. Center-based care typically serves more than 12 children and can be part of a larger institution. Family day care provides care in a caregiver's home, often for infants and toddlers. Informal care involves parents caring for each other's children as needed. Studies have shown that day care can positively impact child development, though higher quality care seems to lead to better social outcomes. The effects of day care depend on factors like a child's home environment and the amount/quality of care and interactions they receive.
