Here's an article where 5 women explain why they chose not to have any children. http://shine.yahoo.com/parenting/5-women-explain-why-chose-not-kids-165300500.html
Did you ever think about not having children? Like some of the women, would you have had more time to enjoy your husband? Would you be divorced? Basically, why did you have children instead of not having children?
If you don't have time for the whole article, some of the reasons included 1.) having a fulfilling life already, 2.) growing up with dysfunctional parents or other close relatives/friends who were miserable because they had kids, 3.) getting to sleep in late, travel the world, not spend the money on kids, 4.) a biggie ~ not feeling the maternal impulse.
Would you life be as happy/fun/fulfilled if you hadn't had children?
