    Putting children in daycare helps working parents take their minds off childcare. 1.

How daycare negatively affects children is related to many factors. One study has suggested that some children who spend long hours in daycare centers experience more stress than those who spend more time in a setting with a mother.

Another study has shown that children who are shy have a higher level of the hormone cortisol (皮质醇) which is released when an individual shows signs of stress. 2. And as a result the child may not mix well with the other children and the teachers at the daycare center, a situation that can cause stress.

Another negative impact of daycare is that there is less communication between a mother and her child. 3. So it is essential for a child to develop a deep bond with his or her mother, since this will lay the foundation for all the relationships he or she will form later on in life. Children who spend a lot of time with their mothers experience healthy social and emotional development, while long hours in daycare can disrupt this bonding. Children who lose out on precious mother-child bonding are observed to have behavioral problems as they grow older.

Children in daycare centers also feel unprotected compared to children at home. In a daycare center, when one caregiver attends to more than one child at the same time, she may not be able to look deeply into why a child is mixing well or not. 4. Another negative aspect of daycare is that children there are more likely to fall ill if they come in contact with sick children.

5. Well-maintained daycare centers contribute a great deal to the overall development of a child by providing a structured environment. Children become more social by interacting with other children of the same age, and learn new activities that are not always available if they arc brought up only at home.
