I live in a house with 2 yr old daughter, my 2 siblings, and mother. I am currently saving up to move out soon. Lately I have been arguing a lot with my sister cause she screams a lot at my daughter which I do not like. My daughter goes to all room all happy and once she drops something she screams at her kicking her out on a daily basis. My daughter usually walks in there when I am cooking or cleaning the whole house (since nobody cleans here but me.) I have tried speaking to her but it is like speaking to a wall. I told her I do like her screaming at her and if my daughter does anything she does not like I will come and get her. No need to scream or kick her out the way she does. She says then tell your kid to not come in here to which I responded if you dont want her in here close your room door. Simple. She said no I will not close it. Just don't let her in here. She is almost 30 acting like a child. She is no one to scream at my child.
