I get this. For years I found it uncomfortable to watch, and like dreemyweird said above, a deep part of me didn't even understand/believe that mothers and daughters could really love each other (even though in RL I know there are many daughters and mothers are happy together) as that wasn't my experience at all.

I'm actually writing a happy child/mother relationship now, for the first time, after years of writing screwed up ones because I didn't have any other model, but still feeling bad and guilty about it. It's very therapeutic. It is a son/mother relationship, though. I think writing a healthy daughter/mother relationship would still be too much for me.
