I guess I just miss having the child that was so dependant on me, I have three others that still are, It's just hard accepting your children are growing older and so are you.
I would say (and, incidentally, my wife agrees with me) that we don't miss having children who are dependent on us. We always liked the idea that they were growing up and ultimately would take on their own responsibilities. I can never understand people who say they don't want their children to grow up and leave home - isn't that the whole point of raising children, that they can take on the world as capable adults?
My wife has a friend who has two daughters, now about 25 and 22. When they were teenagers she used to get really upset about the fact that they would soon be off to Uni, saying how much she would miss them (yes, probably she would) and that they were "her best friends".
My wife told her "No, they're not, they're your daughters and there's a world of difference".
Anyway, I like having children who are growing older - it's how it should be.
