At about of age, children can better tolerate being separated from their caregivers; this is because they have developed a working model of that person's presence that allows them to venture out into the world.

At about three years of age.

Explanation:

Attachment theory seeks to understand and explain the way that children interact with their main caregivers and how different patterns of interaction inlfuence the child's ability to form and maintain intimate relationships with others in the future.

According to this theory, that was developed thanks to the contribution of different psychologists such as John Bowlby and Mary Ainsworth, babies that are seven months old begin to develop a strong attatchment to one of the caregivers, and show distress and anxiety when they are separated form him. In the next stage, toddlers around three years old have been able to develop a working model of that caregivers presence that gives them enough security to venture out into the world.
