Report it. The Daycare Administrator is not only abusing your son but also traumatizing him.
I believe, Child Physchology is required in running a daycare so that Daycare Administrator is not only physically but also emotionally and intellectually abusing your son in which with this ground he/she might not only be out of the school but also be inprisoned. I agree that you asked other parent's, and most probably they also has the same issue..
