周日:一早起来,没提昨天的事,让他洗衣服,擦马桶,干活。态度都可以. LOL. You shoudl praise him for that. Someone told me before, Min the bad, but Praise the goood. I am sure you see your son's soft and sweet side, you are the only one can help him in the house at those situation. You have to stay calm, especially while your husband is frustrated as well. Remember, 生气慢半拍 to both of you.
Do not try to fix the problem on the spot, (unless it is emergency) It can only make it worse, write it down, choose the right moment, sometime even take up to a few days....
He is a good child, just needs a lot good attention, like many kids at his age.
Last, every child is different, 镇压 might work for some, but I am afraid your son is not that case..
