If she doesn't yet, she'll love it in a year or so. Godmother Altariel needs to get a few of the books for her - they are gorgeous. Make sure though that you get ones which Lauren Child did actually write as books, pre-TV-series; there are some more recent books which are book-versions of TV episodes produced post hoc, which simply aren't such good books (even though the TV eps were fine, if that makes sense). Basically, just make sure the book actually says "by Lauren Child" rather than "based on the TV series inspired by the work of Lauren Child" or similar.

And then when she's six or so, if she's enjoyed Charlie and Lola, definitely try her on Clarice Bean!
