We got two Lottie Paris books from the library recently, and my daughter particularly loves them. They are:
Lottie Paris Lives Here, and
Lottie Paris and the Best Place.
One is about a little girl living across from the park, having fun, getting in trouble and getting time outs. The other is about making a friend at the library. Both are honest and real, we can totally relate to them. Plus, she seems to have a single dad, and non-traditional families always get bonus points with us.
