So my daughters and I have comandeered my husbands Christmas present from my mom! We're LOVING his Kindle - lots of free books found for my six year old and I... but my four year old is desperate to read her own books on the Kindle - I found some books today, but they are $.99 each for Bob book types stories, just a few pages and a little too easy for her. Any suggestions on easy readers for the Kindle??? We'd love them to be free, but I wouldn't mind paying a little for some good ones. She is reading the First Steps during school so that's the right level, but can't find those books for the Kindle. Of course she doesn't HAVE to have books on the Kindle, but she's so excited and loved reading the one I bought for her Pink Pig, so it'd be nice to have more so she's not feeling left out.
