Children need their mothers’ presence, both emotionally and physically. Mothers’ heartbeats and breaths synchronize those of their babies, teaching the little ones to regularize, thus stabilizing some of their bodies’ most important processes. Mothers’ breasts automatically change temperature to warm up or cool down baby as he needs. Her milk naturally changes itself to fit his unique dietary needs at every moment of infancy.
Professional caregivers work within the context of a center-based care (including creches, daycare, preschools and schools) or a home-based care (nannies or family daycare). The majority of child care institutions that are available require that child care providers to have extensive training in first aid and be CPR certified. In addition, background checks, drug testing at all centers, and reference verification are normally a requirement. Child care can consist of advanced learning environments that include early childhood education or elementary education. “The objective of the program of daily activities should be to foster incremental developmental progress in a healthy and safe environment and should be flexible to capture the interests of the children and the individual abilities of the children.” [1] In many cases the appropriate child care provider is a teacher or personal with educational background in child development, which requires a more focused training aside from the common core skills typical of a child caregiver.

More specifically, further research indicates that children being cared for by siblings or similarly-aged children (a trend more commonly seen in agriculturally-based cultural communities) have certain psychological and developmental effects on those being cared for. These effects include but are not limited to: mother-child attachment, emergence of childhood developmental stages, formation of playgroups, development of social responsibility, sex differences, personality differences, cognition, and motivation and performance in the classroom.[2]
