Thanks for the suggestions for books. I've seen the "names of God" devotional and it looks promising.
We have been going through the Bible itself in the past, and even with this book read more than is required most nights. We use the ESV since our church uses it, and I want the kids used to it and the theological language. (My six-year-old even knows what "behold" means!) We do have an international children's Bible but I don't know if we'll need it.
