Do you treat all of your kids equally all of the time?
ols, I agree with you on this subject. I only have one grown, but during different times of life my kids have gotten more or less time, attention and finances. I don't expect that to stop anytime soon.
In college my parents helped my sister more than me. I could keep my grades while working, she needed more study time. I didn't begrudge her that, nor resent my parents for it.
I know at certain times in everyone's life they need their parents more. Even at my kids ages this happens. But this is consistent and on going and completely different. They dont need to not pay, they dont want to, so they dont!
