I got my daughter a Kindle HD 6 and was setting it up the other day. I signed into our account and went through the setup, and I was a little concerned to see many of the Kindle items I'd purchased show up on the carousel. A lot of these books were not appropriate for an 8 year old girl and I wanted to find out if future Kindle purchases are going to be showing up on her carousel. Was there something I missed during the setup that might have caused these to show up? Is there some setting I can change to ensure they don't from now on?
