She screams at her children every morning and every evening. All three. The little one - girl aged 4, was crying and moaning 'I'm tired mummy I am tired' and other similar wails. She sounds hard to handle, but then ther mother screams and shouts at her 'SHUT UP SHUT UP SHUT UP'. she counters everything the little girl says 'DO YOU? ARE YOU? WOULD YOU? It's really horrible to hear. Other neighbours around us have all commented but nobody has said anything.
The girl sounds distressed always and at the weekends it's often worse as the dad is there too and they are all screeching. I dont think they hit them but the pitiful crying is incessant.
Anyway i just shouted loudly over my fence 'STOP SHOUTING AT YOUR CHILDREN X X X YOU BULLY'
She brings me out in a sweat as we have had three confrontations before and she has called me obnoxious names. I am selling up and moving as i can't stand it but I almost feel better now that I kniow I am not going to stay and listen to it all....I feel a bit emboldended to tell her to stop abusing her girls because that's what it sounds like. 
Should I stay schtum and not get involved, especially as trying to sell my house and all this crap will have to vbe declared?
I might get some serious stick from her now I have yelled over fences but I feel badly for her girls.
Maybe IABU to call over at her. I would not dare go round and face up to her as she would hit me or at least totally annihilate me to my face. She is one of the big 'local family mafia' and reduces me to sweats.
I dunno. I was shouted screamed abused and yelled at as a child and to hear it happening in your own back garden and continue to just ignore feels badly out of order.
Please feel free to flame me. I really dont know what to do and i should probably just steer clear.
