I noticed wen one of my kids acted out I always reacted but now I just sit and ignore them while their doing anything and everything to have u notice their acting out and doing it to get attention. So wen they see ur not fazed on their lil Temper tantrum they just stop doing what their doing because they know its not working and they not about to get their way.
