D.P.
ask the teacher how long it takes him to settle down after you leave. If it is minutes, then he is just making a fuss over you leaving. If he cries all day or frequently, he probably does not like it there. go with your gut, if you dont like the teachers and something doesnt feel right, pull him and find new care. try picking him up early a couple of times unannounced. see what is going on, try to spy on him...if he looks happy, he is probably okay. if he is sad, not playing with anyone or if they are not treating him good, pull him!
