I think over-parenting can be disastrous, particularly emotionally. I had what you might call a "strict" father (mother passed away when I was young), but he was never a helicopter parent. My sister and I were always expected to do things well, but we were never handheld along the way. I finished second in my high school class, and everyone always seemed so surprised when I told them that I never had any help with homework or school projects. I was just told to do my best (whatever grade that might result in). And while my dad was probably a little on the overprotective side when it came to safety, the ability to "figure things out" myself helped drastically when I finally went out on my own.
My wife on the other hand... I hate to use the word "coddled", but I am absolutely astounded at how many basic tasks and life skills were never taught to her. She never learned that you can't dump all of your clothes in the washing machine and set it on hot. She never learned that not watering the yard will quickly kill all of the grass. When I was talking about scheduling a prostate exam, she asked if I could schedule hers too, and I had to explain that women don't have prostates (when she was a kid, she was horrified the first time she had her period because no one explained what that was either).
She doesn't want to get a job because she says she won't have enough vacation time for visiting family, so she's currently living off my income (we don't have children). Her brother finished his PhD over a year ago but has not applied to any jobs and lives in the basement playing video games. I love my wife a lot, but it somehow slipped my attention before we got married that her parents failed her in a big way by doing absolutely everything for her and her siblings. It's translated into a lack of basic adult skills, and I often feel like I'm not a husband in the relationship, but a parent. When I eventually have kids of my own, "figure it out yourself" is going to be a common refrain, because "I'll take care of it" apparently results in a disaster.
