Why not discuss death with her? My son (about 5 at the time) was seemingly obsessed with death after we had a couple deaths in the family. He was always talking about it. It scared me that he could be so interested in it, but he was. So we talked about it...over and over. We explored everything that he was interested in and I explained as much as I could. Once he got the attention that he needed and expressed things his way (by learning everthing about it) then he was ready to move on.
Kids are like human sponges, they soak everything up. But you have to give them the information to soak up. Once they have, then they are ready to move on to something else.
I hope this helps some.
