limits of imagination

caleb has a great imagination. he loves to have his cars drive over to each other and talk about what they like on their toast (jelly, butter, honey, etc) or what kind of cereal they want for breakfast. he tries to put his diapers on stuffed animals and wants to clean their ears with q-tips. cooking is a favorite thing so any spatula all of a sudden whips up some eggs and anything even remotely cup-like needs to be sipped and shared. most recently, caleb has become infatuated with guitars and playing "king Jesus is all" and "pharaoh, pharaoh". so now sticks and forks and anything long and thin becomes a guitar to strum. it's all super cute.
but...
have you ever read "Go Dog, Go"? we don't have the full version, just the kid's board book and caleb loves it (calls "dogo"). he especially loves the pages with "stop dogs stop" and "go dogs go". but here's the thing. he doesn't actually realize there are dogs in the book except on the page where all the dogs are more realistically colored. that page he freaks out because of all the dogs. and the rest, he's totally oblivious. how can a little baby fork be a guitar but a dog, if colored green, must be some sort of silly monster? what a fun mind to get to know!
