I want to mix up the type of reading I do with my almost-4-year-old beyond all picture books. We have some early readers but I find them to be rather boring since the focus is on keeping the words/sentence structure/plots short and sweet. I looked on Amazon for chapter books, but there are SO many options it's sort of overwhelming. And I know the age/grade recommendation is for reading level and appropriateness, but I don't know how to gauge it if I'm the one reading and she's following along.

So, does anyone have any recommendations for chapter books/series that might be good as a first foray for a 4 year old? Thanks for any ideas!!

ETA: Or maybe there are interesting early readers or similar that people would recommend? We've done some Elephant and Piggy, Little Bear, and a couple others. They're fine but don't seem to capture her attention (or mine) all that much, and they are rarely in the category of repeat requests. They come out when she's bored with the current selection of picture books.
