In the first years of a child's life it is essential that he receives the care and attention he needs. In order for children to receive the best care and attention, it is better for them to stay at home with their parents because this has more influence on their development. However, to make a living, parents must reenter the workforce, which leaves them to decide what care would be best. That said, most parents are left with the only option of sending their child to daycare. Since parents are left with that option, the most important factor they need to consider is the quality of the daycare, not the price or convenience. While daycare may be convenient and affordable, the quality may negatively affect children. For a long time, women would stay home with their children while men went out and worked. Women were able to bond with children, create attachments, and help children develop physically and mentally. They were also able to give the children the care and attention they needed. With the advent of the nineteenth century, nurseries were opened so that these women could be of help during World War II. However, after the war ended, women were able to return to being stay-at-home mothers. As the years have passed, our economy has made it increasingly difficult for women to stay at home. Women were left with only one option: send their children to nurseries, whether it was profitable or not, so they could work. Now in the article, How Early Child Care Affects Later Development, the National Institute of Child Health and Human Development administered a study to conclude whether long-term child care affects the cognitive and social-emotional development of a child. In order for them to achieve success... in the middle of the paper... they are influenced by both temperament and nursery. The researchers called the participants by telephone and managed to recruit one hundred and twenty-four children. Each participant was separated from each other upon arrival until the procedure began. Two children of the same sex were then paired together and placed in the playroom for approximately twenty minutes. These gaming sessions were videotaped through a one-way mirror and subsequently analyzed using scales designed to measure social behaviors. Once all the data was collected and analyzed, the researchers were able to conclude that kids who had just started daycare show aggressive behavior due to overstimulation and also that daycare decreases the child's social behaviors while at home these increase. It had also been shown that the child's temperament was an important factor in relation to his social behavior.
