From changing diapers to homework to don't drink and drive, the sacrifices for being a mom are immeasurable, but the bill is always marked 'no charge'. 

When I was very young I remember a country song that used to come on the radio that talked

Chris Hondros, Newsmakers

about all the things that came along with being a mom and at the end of the day there was 'no charge'.  The song is called 'No Charge' by Melba Montgomery and It went to number one on the country Billboard chart in 1974.

Happy Mother's Day to all moms and thank you.
