DH is really pissing me off . 
We have a 5yr old and 3 other DC . The 5yr old has an awful attitude at the moment .
She's ungrateful , always wanting more , says unkind things to her siblings and if she doesn't get her own way , she cries a bloody awful cry , much like a baby 
I asked her to take her bowl in to the kitchen . She replied "why do I have to do EVERYTHING and you sit there and do NOTHING!" 
I told her to stop her cheek and take her plate in .
After teeth brushing it was time to leave for breakfast club . She stropped on saying she wanted something to eat (she wasn't hungry , she had ample breakfast - she does this all the time ).
I said no it was time to go . So she started talking to me like rubbish , real attitude , stamping feet saying I was mean , I never let her do anything yada yada yada.
She then flung the towels off the rail. I made her pick it up and told her there was no screen time tonight until she can show good behaviour .
All this time , DH was stood at the stairs , watching this , not saying a word . I repeated to him that there was no screen time , hoping he would back me up . He said "ok". 
So obviously DD ran to daddy ; she wants him to do everything etc .
Rightly or wrongly , I retorted by saying I'm not doing anything else for her until she can speak to me properly .
DH is quick to say they are badly behaved but will do f all about it .
My kids think I'm mean and shouty and DH Is calm and fun. He's calm because he sails through life knowing I'll sort everything out 
AIBU or should he have intervened when he saw the behaviour ?
