Hi Shadowfire!
I'm thrilled you are interested in my curriculum. I designed animal play after struggling with my K4 year with my little boy. I guess you could say that I designed the early learning curriculum I wish I had had! I am now using it with my 3 year old and she loves it.
It is not time consuming at all. If you cover everything you could easily do it in under an hour, or you could take a little longer if you added in extra books and such. I don't think the Bible is overkill with Animal Play. I have a Bible time scheduled, but I don't really add too much into the rest of the subjects. I love the Bible and I love teaching it to my children, I just don't think it's necessary to teach it across the curriculum.

The Bible Rhyme book I chose because it tells the Bible stories in such a wonderful rhyming way. I think it's an awesome literary resource that anyone can enjoy.
My goal with this curriculum was to make learning fun and get children excited to do "school". It sounds like you've already done that! Keep up the good work on all the extras you do. It sounds like you have a very learning rich environment already!
Let me know if I can answer any more questions!
Joy
