DD1 is 6, almost 7 , and has Aspergers with sensory issues .
Her behaviour has me on my knees . I know a lot of it she can't help but I'm really finding no joy from parenting right now 
Dd2 is 4 and is copying some of her sisters behaviour and pushing boundaries as dd1 takes up most of my time .
The main problems at the minute (not all related to ASD):
Constant back chat and eye rolling at the most simple of requests - this is getting on my last nerve !
Ignoring me when asked to do something - eg , put on your shoes .
Lashing out / angry outbursts over minor things (this is ASD)
The need for every minute detail to be "fair" if it's not it's constant arguing and explaining as to why it can't possibly be corrected / fair (ASD) - this is so exhausting .
Having to be repeatedly told to stop doing things - eg - take your feet off the wall (and repeat ) . They both ignore .
Speaking rudely to me and telling siblings to shut up .
Bedtime is a disaster and my temper is frayed every night .
And the constant ducking fighting !
I use 123 magic and confiscate things , bring them inside , send them to their rooms but with dd1 this has little effect .
I really don't think she grasps how bloody rude she is being .
They both have tablets which are removed due to bad behaviour but I feel I'm constantly removing them !
I've spent all afternoon making a star chart each for them to begin this weekend .
I need tips on what I can give them stars for and also what sanctions I can use? (With the ASD in mind).
Help please !
My only other option right now is to drown myself in a bath of gin !
