This could be me with my ds also four. I'm sick of shouting, sometimes screaming. I feel like a pretty crappy mum right now.
I've tried time out, times in naughty step, calm down chair, reward chart, traffic light system, counting to give.
He just doesn't listen, I get annoyed I shout, he shouts back its getting ridiculous.
I plan tomo to try my best to stop yelling, even walk away and calmly talk to him, I'm stopping TV, I'm sure the more he watches the worse he gets, and more outdoor, after nursery Park library, garden a walk anything rather than TV.
He starts school this year too, he's fine and will behaved at nursery.
I'm sure it's a phase, for both us its so hard x
