In the book giver why do the birthmothers never see the new children?

In "The Giver," the birthmothers are not allowed to see the new children they give birth to because they are not meant to form emotional attachments to them. The children are immediately taken to the Nurturing Center where they are cared for and raised by a team of professionals to ensure a sense of detachment and lack of personal connection from the birthmothers. This is part of the community's efforts to control and regulate human emotions and relationships.
