Parenthood Successful measure you How
That is a really tough question to answer, because it's subjective. What do *you* consider "success" in parenting? For some people, it means having children that actually lived past their teenage years (meaning the parents didn't kill them!). For others, it could mean having a strong relationship with their kids, even if the kids are not living church standards. For others, it means all their kids are active in church, were sealed in the temple, and have stable, happy home lives.
All of us have our own standards as a measurement for success with our kids. I still haven't decided if I'm a success or not; my kids aren't old enough for me to judge. (yes, my son will soon be 21, but he has yet to have a significant life event to determine who he is.) So my criteria for my success as a parent is how my children will live their lives. Do they have any common sense? Can they make important decisions (or any decisions at all) well? How do they treat other people in every day life, and especially in difficult situations? Do they follow through on promises? etc.
In my opinion, of course.
