Book Review Request

I tend to collect children's lit, in advance of my daughter wanting it. That way, there will be sufficient reading material around for her when she's ready. She lives in her head so much as it is, I suspect we will lose her into books for hours if not days once she gets the idea.

Anybody know anything much about this series?:

Must trot off to bed now, since I have to work in the AM. Any predictions on whether the baby will sleep through tonight?
