Across Britain, burnt toast will be served to mothers in bed this morning as older sons and daughters rush to deliver their supermarket bunches of flowers, But, according to a new study, we should be placing a higher value on motherhood all year.

Mothers have long known that their home workload was just as heavy as paid work. Now, the new study has shown that if they were paid for their parental labours, they would earn as much as＄172,000 a year.

The study looked at the range of jobs mothers do, as well as the hours they are working, to determine the figure. This would make their yearly income ￡30,000 more than the Prime Minister earns.

By analysing the numbers, it found the average mother works 119 hours a week,40 of which would usually be paid at a standard rate and 79 hours as overtime. After questioning 1,000 mothers with children under 18,it found that ,on most days, mums started their routine work at 7am and finished at around 11pm.

To calculate just how much mothers would earn from that labour, it suggested some of the roles that mums could take on, including housekeeper, part-time lawyer, personal trainer and entertainer. Being a part-time lawyer, at ￡48.98 an hour, would prove to be the most profitable of the “mum jobs”,with psychologist（心理学家）a close second.

It also asked mothers about the challenges they face, with 80 percent making emotional（情感的） demand as the hardest thing about motherhood.

Over a third of mums felt they needed more training and around half said they missed going out with friends.

The study shows mothers matter all year long and not just on Mother’s Day. The emotional ,physical and mental energy mothers devote to their children can be never-ending, but children are also sources of great joy and happiness. Investing（投入）in time for parenting and raising relationships is money well spent.
