D.P.
My son did this most of preschool and his 1st year of kindergarten (he did 2 years)!!! Same thing, teacher said he was fine after about 5 minutes! As sad as it is, they know right where to get to mommy! School was hard for my son, so I think it was a bit of anxiety for him, especially if it was computer day (he is a lefty and had more problems with the mouse than the others, it was set up on the wrong side of the computer for him) Just talk to her every morning before shcool about how much fun she will have, how lucky she is to be able to go see her friends and (my son loved this one...) I need you to go learn new things so you an come home and TEACH ME!!! Then when I picked him up I would ask him what he is goig to tech me today, who he played with ..ect.... It helped a little bit! GOOD LUCK I PROMISE IT GETS better!!!
