I had to laugh because as I was typing this new post to our blog, DS2 said, "Mom, it's not a Leaf Pie, it's a Tree Pie, " LOL - well, there ya go! :-) We were out doing our usual Nature Study and exploring and observing and then the boys were studying the big tree in our back yard. Well that turned into a discussion about what the tree eats and how it survives and how old it is (the big boys were sharing and teaching their youngest bro). . . and then came the question posed from DS3 - "What type of pie do you think the tree would like?" And this was the result! I must admit, I love just watching them and those sweet little wheels spinning. . . so incredibly creative!
