Would it be messed up if I gave my daughter her own room?

I financially support my sister and her two kids. I have one daughter who my sister helps with with because I work a lot. My daughter was used to having all of my attention and me doing everything for her. I work so much because we would not be able to survive if I don’t. My sister doesn’t work. She takes the kids to and from school and cooks everyone dinner everyday. I’m okay with that. However, I do work my ass off 6 days a week, 12 hours a day and I can’t ever just do anything for my daughter let alone myself. I want to get a bigger place but I want my daughter to have her own room again. Most I would be able to afford is a 3 bedroom. Would it be wrong if I gave my daughter her own room?
