Attachment and separation are the stuff of which life is made. The bonds between family and child promote resilience, self-regulation, and a positive sense of self. In this article, the author focuses her discussion on the importance of attachment to children's development. She has cited some theories that can help her explain further. For instance, the theory of Eliot (2000), which states that babies are programmed to grow attached to their parents or primary caregivers due to development in their brain's frontal lobe. The theory of Margaret Mahler (Mahler, Pine, & Bergman 1975) states that children and their parents travel together through a series of developmental phases that enable the children to become certain of who they are. The author also discusses on the variations of attachment in terms of the internal parent, children with special needs, and cultural preferences. The author concluded that by developing a curriculum of trust, teachers can help infants and toddlers, when away from their families in early care, to achieve well-being and comfort as well as the ability to learn.
