Child Development Centers offer full-day child care for children 6 weeks to 5 years of age. The Army provides care in a multi-age group setting. The concept of the multi-age classroom is to provide a family-style environment where the children can learn from and nurture each other. Children experience fewer transitions while in the multi-age childcare setting and therefore can bond more closely with their primary caregiver. Children also benefit widely from opportunities to interact with children who are older and younger, learning important principles of citizenship, relationships, respect, patience, and self esteem.
