i have a 5 year old son that is in kindergarden. he is always telling me he hates me when i get on to him for something he has done. he will not listen to me when i tell him to do anything. he almost always says NO, i dont have to. or he tries to bargain with me by saying something like "if you dont make me i will be good". when he gets really mad he will throw toys or whatever he has within his reach. he will scream at me and alot of times he will clench his teeth and growl. its kinda scary. when i spank or something, it does not seem to phase him one bit. he just goes right back to doing what he got in trouble for. eventually i just give up because it becomes so exhausting. he does very sporatic things. for instance: he was a at birthday party sitting there being very good, when all of a sudden he gets up and walks up to the birthday boy and takes his card out of his hands and goes and throws it in a mud puddle. i asked myself why on earth would he do something crazy like that. and i can not find an answer. sometimes it gets to be so much between the both of my kids and i feel like i just may very well lose my mind if thangs do not change. if someone could help me with some ideas/tips on what to do. i would greatly and forever be thankful.
