please. help. me

I have idea why but my 6 month old fights her sleep. I live with my mom so my everyone just walks in my room whenever (I don't have a lock), get in her face for 2 minutes, & leave. I've constantly asked them to stop, first nicely now I'm cursing them tf out. Even tho she's sleepy, she likes attention & wants to play so she'll stay up playing if they're in her face & scream to the top of her lungs when they leave. Nothing I do will stop her. Pacifier not helping. She's sate, burped, dry. I swaddled her, didn't work. Rocked her.  Even let her cry for up to 10 minutes straight them comforted her. Nothing's working. I'm going crazy. Please help me
