I think she means he's very disrespectful when he speaks. An autism diagnosis is not an excuse for bad behavior, and parents can keep their expectations high for their children on the spectrum. But first you need to understand why the child is behaving as he is:
- Are the basic needs not being met: hunger, thirst, tiredness?
- Does the child get out of completing an undesirable task after engaging in the behavior?
- Is the child trying to test limits?
- Is it attention seeking behavior so that you drop everything and give the child full attention when he is acting up?
You're kind of vague about what you're saying. Is his autism debilitating, or is he in regular classes at school but still is kind of "brushed" with autism?
What do you mean "he has a mouth that's out of this world?"
