So my youngest is 2 and 1/2. His behaviour recently is bloody awful. He could find trouble in an empty room. And he has started constantly "crying" no tears just the noise and it's driving me mad. He asks for things then when I give them he doesn't want them. He isn't sleeping at night either waking 7-10 times and taking an age to settle. I'm exhausted and at the end of my tether. today he has emptied every box in the play room rather than do the activity I had planned for us. His brother has autism and he is beginning to bully him by taking toys off him and pushing him. It's shit! I'm so fed up this is my fourth child the others are 14, 12 and 4 and they were never like this. HELP. What's the best way to deal with this please.
