For years, we never made ice in our freezer as we just did not really need it and we rather saved the freezer space for ice cream instead.  We finally decided that it was time, and after Stuart cleaned out the ice box, we now have ice.  The boys were thrilled every time we brought out the water pitcher with ice to the yard lately.  They would rush over to get their icy cold water. They also enjoyed having some ice cubes in their water thermos bottles and liked shaking the bottles to hear the clinking.  Who knows how much fun the ice had brought to the boys!  As a result, they have been drinking even more water than usual too.
