Grandparents help a lot with raising kids

It seems a lot of parents rely on their parents for help with the kids.

A study finds that between 1998 and 2008, 70% of grandparents took care of their grandchildren for at least 50 hours a year.

While some just babysat occasionally, others provided care on a daily basis.

62% of grandparents provided some form of monetary support to their grandchildren, mostly for investments and education.
