well, from experience, this is partly an age thing. my son will be 3 tomorrow and has also been in daycare pretty much his whole life, since he was 4 months old. part of it is age and pushing his limits, part of it is learned from other children. is there another person he spends time with besides you and daycare? does he hang out alone with dad or grandma? it's possible another person is giving him what he wants all the time, either cause they think it's fun which is usually a grandma thing, or to avoid the conflict. either way, children get used to that convenience very quickly. my son hangs out with dad and grandma every weekend cause i work on saturdays. and grandma feeds him candy all weekend, so when he comes home and i won't give him sweets, he tells me those same things, that he doesn't like me or he tells me to leave him alone, or he'll hit, bite, kick, or just throw an all out fit. has anything changed recently? maybe a move to a new place, a new room at daycare, or a new teacher? also, i think it's ridiculous that the daycare is acting that way. i have been using the same daycare from the start and have never had that problem. there has been times they have called to let me know what's going on, but they never tell me i have to pick them up because they are misbehaving. at this age, it should be something they expect and are prepared for. good luck.
