Hmm, I'm posting without reading everything, cos otherwise I'll be late going out! Ok, so I'm approaching this from a psych perspective, which is statistically speaking parenting definately makes a difference. If you have a selection of 'good' parents, their kids are more likely to function happily in society, BUT, some wont. If you have a selection of 'bad' parents, their kids are more likely to not do so well, BUT some will. Sometimes parenting thats good enough for some kids to thrive, just isn't enough for other kids, it can be exactly the same type of parenting, some kids just need more, or less, or different. I think it comes down too, if you feel your parents did the absolute best that they could, then it's probably good enough. If you feel your doing the absolute best you can, then be confident in your parenting choices. My parents made mistakes, but overall I feel they did they best they could with the resources they had at the time. If the resources were different, then my expectations would have been different too. And siblings tend not to take up the same ''space'' that's occupied by another sibling, like, if one sibling is known as the smart one, then the next one probably won't try to compete with that space, but is more likely to take a different space, like the funny one. Or in some cases, the black sheep, it may be a dodgy spot, but it's still a spot! (Well, that's what I used to tell my parents).
Having said all that, no one really knows for sure. And there will always be a situation that disproves everything I've just said (but statistically, that's bound to happen too!).
