I absolutely love this series. I read a few chapters to my 5-year-old every night before bed, and she is always begging for more. Annie Barrows is so great at thinking like a kid, remembering how they genuinely interact with each other and what they're interested in. It's also nice that the kids stay the same age throughout the series. In the Ramona Quimby books, for example, Ramona is a year older in each book, so they can get beyond your child's level a little in terms of content, which is too bad if she starts off loving them and wants to read them all.
