I have a three year old on and I'm at my wit's end. He's naughty, and I can't seem to find a punishment that works for him. He kicks, screams, bites, hits, smacks his baby brother, tips things upside down such as baby chairs, toys, etc, doesn't listen to me at all, continues to do things when I've told him not to do it. He won't sleep in his room, he's in mine and his dad's room. If we try to put him in his room he screams. We've tried leaving him to it but he screamed for literally 2 hours with no break and made himself sick. I understand that this probably doesn't sound like much but it's getting unbearable. I spend my days shouting at him and I hate that I yell so much - especially when all it seems to do is wind him up more! I've tried ignoring the bad and praising the good, sticker charts, but I'm at my wit's end. He's known as the naughty kid in our family and it breaks my heart. I should caveat this by saying I absolutely adore him and when he's good, there's no better child to be around. But this behaviour dominates around 70% of our day and I don't want our days together to just be me shouting at him and him feeling like he's being naughty. Anyone got any tips, or have been in the same boat??
