It’s a very valid question but the time you mentioned is ridiculously long. No body takes off for that long I believe.
As far as working women are concerned in most of the countries they’e allowed to have a reasonable amount of days off work so they could have babies and all that without losing their jobs and company pays them as well.
There are many couples who’ve successfully manged their lifestyle with both parents working and yet taking of their kids. It’s too advance now a days.
What I think is there are very few females who actually pursue their career after getting married because it usually doesn’t workout very well once you’ve more than 1 kids. Initially it’s like hey we can manage and then when you’ve more than one it’s very difficult.
Parents who value their careers more than their children’s grooming they don’t leave their careers and leave kids in the hands of baby sitters or day care schools. But parents who value that usually the mother quits the career and stays home so she could spend enough quality time with her kids to groom them well.
I think it depends upon what you want for your kids as a parent and if someone out there’s saying it doesn’t effect children’s grooming he’s kidding.
