I hate hot weather. Even though our summer has been comparatively mild, I start sweating as soon as I get outside. But the kids need physical activity. So we played the pushing game today. I sit on the floor and the kids try to push me across the room. They love it, we connect both physically and emotionally, they get to work all their muscles, and nobody gets hurt. We even did this during the last trimester of my pregnancy.
Tomorrow we might do a jumping pile with all the pillows and cushions in the house. :)
