okay so, for context I am the oldest of 5. 2 brothers, two sisters. I am 17M. in February, my youngest brother (toddler) moved into my room with me (I have a 12M brother he should've moved in with) that's another story, anyway in order to get him to bed, him and i would watch TV in his bed together (he's a cuddle to fall asleep kind of baby) and I'd have him to bed usually before 11:00 every night. during the summer, occasionally my mother would take him out for my room to sleep in hers for my sanity. this was nice initially, but it became recurring and eventually it got to the point to where after months of sleeping in my room, he got adjusted to going back to his moms room. this isn't even where it gets bad. She then introduces a tablet at bedtime, which again, initially was not an issue, he was distracted at night and it gave me some peaceful time to play video games. but again, it became a consistent nightly routine, and he got used to it. now he wouldnt go to bed without it, and occasionally would cry to go to his moms room. MIND YOU, he didn't do this when he got adjusted to sleeping in my room. he now gets away with going downstairs several times a night for whatever fathomable thing ( chocolate, food, milk, etc) which he does not need he is well fed and only needs to come upstairs with water. he screams to get out of my room every night, wrestles me to leave my room, cries over anything, and the worst part is, I am to blame according to my mother. I try to watch his tablet (THAT I DONT WANT HIM HAVING AT BEDTIME) with him, I try and watch TV with him, I try and play with him for a little to get him tired, ANYTHING to get him to settle, but it is now just constant running to leave my room and scream and cry. I think this is a case of unregulated tablet use, along with excess sugar, but Obviously since I know nothing according to my mother this is simply my fault. She says that if we don't get along, I am going to lose my phone for a week, (I am 15 years older than him) and that she needs to work in the morning, but simply if she hadn't gotten him adjusted to doing whatever he wanted, or caved in and gave him a tablet, chocolate, or food or even being allowed to come down for that matter, this wouldn't be an issue. I don't understand how this is my fault and my hands are tied. am I the asshole? is there something I don't know or can do differently? how do I respond to her about it in a way that she could understand without coming off as rude that THIS dilemma wasn't caused by me or my lack of bothering? Please help. thank you
