Wow, what a great question! It’s interesting because adding fun was a lot easier when the boys were younger. We could do creative projects or just get outside, but now that they are older, we are heads down in study a lot of the time.
One thing we try to do is take a walk around the block with our dog. It’s good to get some fresh air, relax and just enjoy a breather before heading back to studies. We occasionally go out to lunch. This is especially true on Wednesdays when we go to taekwondo during the day. TKD alone is a break from the routine, but grabbing lunch afterwards lets us sit together and just talk before finishing our school day.
While we are in our co-op, there is little time for fieldtrips. There is so much to accomplish week to week that adding in trips just makes us cramped for time the remaining days. Fortunately, the co-op ends right before Thanksgiving, so we have a couple weeks before Christmas to be more relaxed. We bake, see Christmas sites, hang out more with other people in addition to schoolwork.
