I just got done reading this book: 15 Minutes Outside, 365 ways to get out of the house and connect with your kids. By Rebecca P. Cohen. My boys and I have been trying to go for walks each morning before school. One fun game to play while walking is the "cat game". You call out CAT when you see a cat, the person who saw the most cats at the end of the walk "wins". Last night, my boys played and played with an old umbrella stroller. We have a slight hill in our backyard, they took turns pushing the stroller down the hill, they even took running starts to push. I bet they were out there for 30 minutes or more pushing that thing! What ways do you get out and have fun with your kids?
