Just read the Guardian article, and clicked the link in it to the Daily Mail's article on the negative effects of working mothers. Right at the end, this is the part that was the nail in the coffin for me:
"Meanwhile, a U.S. study has found that growing up in a clean home can boost youngsters' exam grades and even the salaries they earn as adults.
The study of 3,400 volunteers over 25 years found that the length of time a child stayed in education and their future earnings was directly linked to the hygiene in their homes."
That's my child's education f*cked then!
