What is your memory with your family in childhood? Around 30 years ago, children would often help to do housework, but now, children don’t do that. The time to spend with parents is important for children. Now, Japanese style of childcare is gradually changing. There are some differences as the number of working mothers, children’s after school activities, parents being less strict show ways. These changes are some problems. However, the Japanese sleeping style is the same, it’s part of Japanese culture. Some problems should be got better, but cultural style should be taken over. Parents make an effort to take care of children and hope their happiness.
