Just a thought, but is it possible that its just the finality of the year setting in? My DS6 just finished up kindergarten and on the day that they had their K graduation when I walked into the classroom he was smiling and playing with his friends. He then came over to give me a hug and immediately buried his face in my shirt and started crying . When I asked him what was wrong he just told me "I'm just too stressed." He later told me that he was worried about missing his friends, missing his teacher, which teacher he would have next year, which kids would be in his class, what kind of things he would get to learn in first grade etc... He's come around since then but still tells me once in a while that he's "a little bit sad" because he misses school.
