I'm a mommy still trying to figure this out too.
DISCLAIMER: I have only one child so some of this is MUCH easier for me and I don't know the difference not having a non-stimmy kiddo...
LAUGH: I used to give parenting classes before I was a parent! I had all the answers and don't tell me I didn't... then Mase arrived and ONE week later I wanted to call ALL the parents I had spoken to in the past ten years and apologize... yes, one week... the one thing I do stand by and always will is reading to a child is soooo important.. even if they are asleep or sitting on the toilet... ok.... you can stop laughing now...

As far as what calls for discipline and what is to be ignored. This is my philosophy... "Will it matter in five years?" Will it matter in five years that Mase rolled in the mud with good clothing on? No, I can wash them. Will it matter in five years that Mase yells at his parents? Absolutely. Now granted, some days this approach is very difficult to live by, but I truly try to stick with it.
Also, rudeness is NOT tolerated no matter what. Your rude, you lose screens (DS, computer, TV, etc)for the rest of the day... do it again and you lose it tomorrow... we have never lost screens for more than two days. Screens are BIG for Mase... I dislike TV very much so I could care less and Dh just hides in his computer desk to do what he needs to do.
Chores??? Isn't brushing your teeth, getting dressed and eating breakfast enough of a chore? Mase must bring in the garbage cans from the curb on a Wednesday. Mase just (and I mean just) starting taking showers un-aided. He can even dry himself off with a towel now. That ladies is a chore that he does all by himself now... one more off the Momma list.
As for what other people say... it hurts and yes you feel aweful...
I know you all have lots of time for reading... but, Temple Grandin's book, "Thinking in Pictures" really has given Dh and me insite much more than any other book written about autism and aspergers... written by an aspie... what a novel idea.
Hugs to all of you today!
