Some daycare centers are co-ops connected with community agencies. In a good daycare center, the workers have some training in child development, health, and safety. The director may have a graduate degree in child development. Good centers have planned educational programs, even for babies. There are some disadvantages, though.
Babies are likely to pick up colds and other minor illnesses.
Because daycare is a low-paying field, staff turnover may be high. Daycare centers are usually busy and noisy, with lots of children. Some babies prefer a quieter environment. If you visit daycare centers, look for their license on the wall. Make sure it's current.
