Tough situation. This is her daughter. The same way your looking out for the best interest of your baby. She's gonna do the same for her daughter. Maybe its time for you guy's to get your own place. Drug addiction is sad and weighs heavy on all involved it may ne good time to separate yourselves completely since baby is coming soon.
Are y'all working on getting a place? I would move out as soon as possible. I agree dont let drug users near your baby. Maybe try talking to your in-laws about it?
Since you live with his parents thats a tough one...
No chance of moving out?
I would explain it to the mom anyway, i wouldnt want a drug user around my baby especially if shes crazy! Hopefully shell understand
Well honestly there's nothing you can do... it's not your house.. it suck ik but that's how it goes..
