Posting on behalf of someone close to me who is really struggling to deal with his children, range of ages, from pre school to teenager. They have no respect for him. Shout at him, swear at him, steal from him. Aren't nice to each other either sometimes. He's recently got full custody of them due to unforeseen circumstances and he's becoming really upset with how they behave. The eldest just walks out when he can't cope, they are up til all hours of the night, struggle to wake up for school.
How can he change this and is there any websites or books for advice that anyone knows of please?
Thanks
