Day Care The effects of day care have been widely debated. One study has suggested that children who go to day care are more likely to show avoidant or anxious-ambivalent attachments than children who do not go to day care. The effects of day care can also be positive in terms of the child's intellectual and social development. Much depends on the quality of the day care setting. In the United States, there has been little effort to ensure that high quality child care is available to those who need it.
