Thats true, when both my children passed that bar (younger is just over 5 and older is 9) a lot of things got much better. But do not kid yourself (pun intended) if you are not sociopath You will feel that You need to care for them for the rest of your life and that always will be a blessing and burden at the same time. And the proportion may not be in your favour (my almost 40 years old brother is still living with my parents and havent had job for years).
