I have a dollhouse bed, and it’s a bunk bed. I exclusively sleep on the bottom nowadays, and I got it when I was younger because I really wanted a dollhouse bed. 
I have a 4 yo niece who comes over just about every week. I do not really like children and I’m not the one who says I’ll watch over her, my mom does. But I live with my mom, so I have to be around her every week. 
my mom spoils her rotten. Every time she goes shopping, online or not, she always sees something and says “This would be perfect for *my nieces name*!” Or just gets her something. When my niece wants something, my mom will almost every time get it for her. 
So whatever, the typical grandparent who loves her granddaughter. (My mom isn’t very old though, late forties.) But we go back to my dollhouse.
My niece LOVES it. She used to crawl into the bottom bunk all the time and when she would spend the night or nap here, she would always want to sleep in my room for the dollhouse bed. I didn’t want that though, I don’t like having a child in my room at night because I usually stay up late and I would honestly not like to jack off around a child, and during the day , this means I can’t really be in my room to do stuff and I would take it somewhere else, and I feel most convenient and comfortable in my bed and desk. 
My sister needed my niece to be watched one day, and my parents weren’t going to be home, so she paid me to watch over her. Cool. I did everything good and I was going to put her to bed when she starts begging to sleep in the dollhouse bed. I decided to cave in, but when I put her there, she kept asking to get up for the restroom, she forgot her milk, etc, etc, etc, until it was obvious she just didn’t want to go to bed. I got really frustrated and I had to put her to sleep somewhere else. After this, I really didn’t trust her to actually sleep in it. 
Recently, when she comes over and wants to nap in the dollhouse bed, i tell my mom i don’t want her to for the reasons I already said, plus I no longer trusted her to actually sleep there. So I always managed to not have her sleep there. But when I leave the house when she’s with my mom, I almost ALWAYS find her In my room, sleeping my bed. It’s even more frustrating  now because I have some bags from shopping where I was going to cut off tags or sort some art supplies I had just gotten, but now I can’t be in there because she’s napping and I have to wait. It’s even worse because my mom doesn’t ask me when I’m not home and just does it, so it’s always a surprise. I’ve told her not to multiple times and she keeps telling me that she’s ‘just a child’ and that she ‘really wants to sleep there’ and ‘she rarely comes over’ which is a LIE because she comes over WEEKLY. It’s also kinda frustrating that she talks more about my niece and how much she misses her over my other sister who is at college Who we actually rarely see.!
Am I the asshole for not letting or not wanting her to sleep there, and for getting upset at my mom for ignoring my wishes?
