I think I'm unusual but interested to know.
I still read to ds who is 12. I stopped reading to his sister when she was about 8 (her choice but that was fine)
Have to say at times it has been a bit tedious but now it is so interesting. I am suggesting books that I "should" have read but never did. So things like The Hobbit, Swallows and Amazons, lots of children's classics. But also rereading and introducing him to things that I love(d). I just get excited about all that we can read together, and trying current books as well.
I do ask him to let me know if he's had enough of it but he assures me he still loves being read to 
Anyone else?
