A child's positive sense of well-being is central to their overall growth and development. With an increasing number of mothers in the workforce, many infants and toddlers spend much time in child care services. Hence it is crucial that caregivers provide a secure base for the child to develop secure attachment with educarers. Given multiple caregivers, fostering attachment in the child care setting can be problematic. One strategy used in some countries is the implementation of a primary caregiving system. The purpose of this research study was to investigate how caregivers in two childcare centres in Singapore implemented the primary caregiving system. A 'before-and-after' methodology was used to find out if change had occurred after the intervention. Results showed that attachment in infants/toddlers had strengthened through the improved educaring practices, collaboration with families, staff team work and employment stability. (author abstract)
