Are they your biological or adopted children?
Take into consideration the childhood developmental stage.
But at that age, the kids are out of the formative years and you need to work more on their social skills. And , share your concerns with their physician in case there is something going on.
Be a role model— action speaks. For example,, knock on their door before you enter their room. You ask them to help set up the table, take trash out, and explain each of their behavior in a language they can understand.
If they are not your biological children, it’s on their mom.
Best!
