How about help regarding a 4 year old who recently started acting out at daycare (i.e. hitting/biting/kicking, even shaking another little girl by the head) and throwing tantrums at home for mom (but not dad) to the point that he is completely irrational and unable to console for up to an hour. This is a little boy whose usual rebellion is to say "No!" or call me "Weirdo!" This had only been going on in the last month. I have had him evaluated by his pediatrician for medical issues (i.e. problems post tosillectomy/adenoids/tubes placed, ear infection, bad teeth, etc). This is a sudden change that is so far from his normal behavior. When I ask him, he tells me he acts that way at daycare because he doesn't like a certain little boy (of which my son is usually excludes from play) and tells the daycare provider, when she asks why he doesn't like to come there, that he just wants his mommy. Any help?
