Every days is a battle just changes wha it's about every day lol. Could be anything from the wrong spoon to just asking them to take their dishes out that starts a meltdown and the two are completely different it what sets them off. My sister-law has boys on the spectrum and in boys they tend to get more hyper than the girls from what I have seen.
They see the world in a different way and I sometimes wish that we could have a glimps of what it's like have to deal with things and see things as they do as it would help us to help them.
Good luck.
