Siblings fighting please read

I know I made a post already about siblings fighting but I didn’t get any comments from it. I just want to repost the comment I made on that post. This is a subject I really need to vent on and get some 3rd party advise on. Going to type out a fight my step daughter who will be 8 at the end of February and my son who is 4. So I’m in my room folding laundry sitting on my daughter. My daughter is sitting on my bed just staring at the wall. She’s an ipad kid and can’t entertain herself, they lost tv/ipad/gaming privileges earlier in the night from a different fight. I had also asked both of them to leave me alone to do the laundry since I was burnt out from all the previous fighting. So my son drags in one of those electronic books the one that talks like “press the red star” so he’s standing with the book on the bed doing the games. My daughter gets off the bed with out saying anything and walks over and starts pushing the buttons obviously my son is getting frustrated he’s telling her to stop and pushing her away. So I tell my son to keep his hands to himself and I tell my daughter to leave him alone so she literally is just standing to the side watching my son play still hasn’t said a word. My son has a couple of these books in his room and my daughter has plenty of toys here also. So my son finishes the book and pushes it away going “all done” my daughter still hasn’t said anything grabs the book. My son pushes it away again and goes “no we’re done” repeat a few times again my 8 year old not talking and my 4 year old perfectly communicating his want to be done with the book. I can hear my son getting frustrated and he’s pushing and scratching again so interject at this point cuz if he hits her he’s gonna be in trouble. And I’m talking to my son in front of daughter he’s explaining to me that its done he finished the book he said the end so it’s done I’m explaining to him that that’s fair logic but just because he’s done doesn’t mean other people are done. My daughter still hasn’t said a word grabs the book again. My son turns around and hits her snatching the book away going again “I said we are done” so now my son is getting in trouble for hitting her which I hate because it’s not fair he was literally pushed to that point by someone twice his age but we can’t go around hitting ppl even if we are angry so I’m trying my best to instill that life lesson. I do snap at my daughter though “ like why couldn’t you just talk to him. Are you physically unable to talk. Why can’t you ask for a turn is it because every time he asks for one of your toys you say no?” To which she stormed off locking herself in the kids room until her dad got home so she could cry to him. To which my boyfriends response was “she’s an only child at her moms house what do you expect (she’s the youngest of 5 between my boyfriend and his ex wife) and that I should have stepped in sooner” but step in and do what?! I gotta explain to an 8 year old about sharing. I’m so over it.
