Over breakfast this morning I asked Theo where hedgehogs live and without thinking he replied correctly. I then asked why a hedgehog has prickles and he proceeded be demonstrate how a hedgehog curls up into a ball so the prickles stick out. Although we had not created the picture yet he also remembered they had poor eyesight, because he remembered our discussion on drawing a hedgehog with glasses. The image was clearly in his head although not yet committed to paper.
