Biblioplan. I haven't used it, but have considered it. http://www.biblioplan.net/p/welcome-to-biblioplan.html

I haven't read all the suggestions, but aside from the most popular choices, mine especially liked Mr. Popper's Penguins and Milly-Molly-Mandy.

I was JUST reading and re-reading that thread this week. I think this is where I am aiming, but I get unsure of myself and feel like I ought to be doing what this, that or the other reccommends. (I would do this anyway, but still.) I don't really have anything to add, but I'm grateful to everyone who contributed their thoughts and experiences. Looking forward to pursuing our interests and reading lots of good books this year. For beginning readers of good quality, I have the first of the CLP nature readers and that has worked well for us. I'm on my second reader with it now, and am reminded of how much I like it. Link to the series here. http://www.shopchristianliberty.com/christian-liberty-nature-reader-complete-set/ I think I purchased ours from rainbow resource. Memoria press year one and two also has good suggestions. (i.e. Little bear)
