I'm sorry intime... to me it sounds like you are implying your way is so much better than mine. I'm happy with our lifestyle, I think my kids are great... they have a strong sense of family and each other but also a great sense of independence, following their passions as they come.
My kids help out and even watch their little siblings but it's not an all the time thing. I did NOT have children just so they could raise each other. I would rather my kids WANT to help then feel obligated, most of the time it's not an issue. I would never make any of my children do all of the cooking and cleaning and caretaking while I was on bedrest, though. That's not their job. :) That would be my partner's position to take over and when I had a rough time healing from my last birth, my partner did step up and take over.
I cater to their strengths but also try to push their weaknesses. I don't think I'm expressing how my family runs very well...I just feel very unclear and misunderstood. <shrug> Currently we are living in a multi-generational set up which is neat and how I grew up. I'm glad my kids get to experience life with their great grandparents and what they have to offer in terms of wisdom. Anyway... I don't think anybody's way is any better than the other, we do what works best in our families.
