HK my dd4 does the same thing, I was gutted to find out dh had been watching the news with her while I put ds to bed. He said last week the first time he didn't have an answer of her was when a transsexual one Eurovision a few weeks ago, personally I would much rather my dd knew about that than war and rape etc. water off a ducks back to her though. I would really stress about her empathy levels if I didn't see her day to day interactions
