Conversations with a four-year-old

Ty definitely keeps me on my toes with his questions. Here are two from today:

Tyler: "Mommy, who made God?"
Me: "Well, no one really. God was the first one here."
Me (seeing that he wasn't quite satisfied with that answer): "God made God."
Tyler: "Where did He get the directions for how to make God?"

Tyler: "Mommy, where do baby animals come from?"
My first response: "Well...(thinking...am I really getting these questions already?)...their mommy and daddy make them." From the look on his face, that was way too much information.
Luckily he was satisfied (for now) with my second answer: "From their mommy's bellies."
