Hi. My name is Sandi. I have a four year old son, Nick. Was just exploring and found this site. Was looking for suggestions on how to deal with some of the behaviors my boy is exhibiting. I am a teacher so I have a pretty good background, but this is beyond my knowledge level. Nick is being defiant and just downright mean at times. He is talking back like a teenager already. He's taking temper tatrums and screaming at the top of his little lungs. I have tried everything I can think of from time outs to sticker reward charts. They may work for a short time (and yes, I am consistant with them) but then the behavior starts again. Any suggestions?
