In the lifetime of a woman, how many maternity leaves does she take? On average it would be twice and very few women I know have taken more than 8 weeks. The way you put makes it sound like women take 6 months+ time off and everyone else has to pay for it.
The way I put it makes it sound like women take 6+ months time off because, oddly enough, women take 6+ months time off. The average in Canada is 39.6 weeks paid leave. Note that that figure is for children aged 1-3, how many weeks paid leave did their mothers take. The average per women will be higher.
The plural of anecdote is not data, and you are no exception.
