Last week David brought home a Caterpillar that he found at his work. Only a couple days later he made a cocoon. A week or so later, today he or she turned into a Monarch Butterfly. I had just looked at it 20 mins before but had missed it when it hatched out of it's cocoon. The kids liked it. Later we let it go outside. It hung around for a while before flying away but the kids got to see it up close.
