As a father, I've always been concerned about my effect on my children... There're constant assumptions that fathers both are not as important in their children's lives as the mother is, and that we simply do not (and perhaps cannot) do enough for our children socially and emotionally. I have tried to really think about my effect on my children and to be a good father, friend, supporter, teacher, etc. to them. I've made mistakes like the best of us but I think I've done a good job.
This news item makes the pretty obvious (at least to me) claim that, among other things, the relationship someone has with their father, tends to have an effect on other relationships later in life. It doesn't really go into details, so if you're looking for tips, you'll be dissappointed. It basically says be there and have a good relationship with your kids. Duh. Hopefully there'll be more research. For now, we'll just have to try our best, attempt to integrate all the other advice, and be a good person overall. Damn. And I thought this child-rearing thing was going to be easy! LOL
