LOVE LOVE LOVE these books. Got them for my kids a while back, were having fun learning the new things in them which in my case is remembering alot of old things. Got them for half price on ebay, so glad I did!! Granted Gage is a bit young for alot of things in the book, but he can enjoy some of it now and much of it later. DD is up for a whole lot of the book now but has some things to look forward to in the future as well. She is pretty excited about alot of things she is reading about :).
