My son will be three in 24 days, but he is still out of control. He screams and shouts at us in temper, hits us in temper. He totally ignores us when asked to do something, misbehaves too often, purposely wets and dirties himself, breaks and throws toys to try getting his own way, always doing things he shouldn't be. He refuses o go to bed every night, keeps on coming downstairs to use the toilet (we don't have an upstairs toilet), if we tell him no because he has only just been, he squeezes wee out so we have to clean him up. We don't know what to try anymore, any tips/ideas?
