If your parenting philosophy is not based on any research or learning about what's best for your child, but instead on what's easiest and most convenient for you, then you're probably doing it wrong. That doesn't mean you can't set boundaries for kids who are old enough to understand them.
I think the way we discard our elderly is closely tied to our self-absorbed approach to parenting. If you don't put in the time and are unwilling to make sacrifices for your kids, you shouldn't expect them to be there for you when you need it.
