Hugs. We often have to chance or cancel plans due to DS's needs and behaviors. It's a way of life for us, but it's still hard at times.
I saw your other thread about your DS2 having visual disturbances. Do you think the behavior issues could be related? I know with my DS, if his behavior is significantly worse than usual it often means he has a headache or other pain. (My DS doesn't report pain, even when asked, so we have to go by his behavior). Could your DS be having migraines or something and the pain makes him act out?

DS, age 11 and always amazing
