One of the books was about a little pig family. The dad, and older two siblings were going on a camp out, and the youngest pig was very sad. So her mother had a great idea. They would not have a camp out, they would have a camp in.
They set up the tent
around the campfire.
They told ghost stories,
The next morning they had cookies and ice cream for breakfast before they cleaned up their camp.
I am not lax enough of a mom to give my kids cookies and ice cream for breakfast (unless in dire straights. Dire, I tell you.), but we did everything else in the book.
Who needs summer for camping?
