Grandparents are willing to take care of their children because they are distressed by their daughters.

Grandparents are willing to help their daughters take care of their children, probably because they are distressed by their daughters and hope to reduce their burden and pressure. At the same time, they may also want to establish a closer relationship with their grandchildren and enjoy family happiness.

In addition, some grandparents may have retired or have relatively free time. Helping with the children can also make the daughter feel more at ease to go to work or other affairs. At the same time, grandparents have relatively rich experience and can provide some useful suggestions and help to better care for and educate their children.

Whatever the reason, grandparents' willingness to help take care of their children shows their love and support for their daughters and grandchildren. As daughters, we should also appreciate the kindness of our parents and give them appropriate rewards and care if possible.
