Has anyone having similar problems to me? I have a ds who is 2/6 and dd who is 4. Seperately their behaviour is really good..together..nightmare! They wind each other up, run riot round house and listen to absolutely nothing i say to them. I have tried time out, withdrawing treats etc but they find it funny. Am i being to stressed bout this? I have 5 children, one with learning difficulties and the youngest being 6mth so this gets me down everyday...can anyone offer any suggestions please..
