Bit rude and very strange of them. I would look to move out and then you don’t have to worry about them!
That is weird and rude. I wouldn’t be allowing it personally. Why does she need the door shut? What are they doing in there? I would definitely move out.
I don’t feel comfortable with anyone alone with my baby behind closed doors. No way!
My MIL did this once so I followed her upstairs walked right into the bedroom after she shut the door, picked my baby up and said bluntly “don’t take baby away from me where I can’t see him, it’s unnecessary and weird, and it makes me feel uncomfortable” and walked back downstairs with him. She’s never done it since and hasn’t brought it up 🤣🤣
I don't blame you for being annoyed... that would bother me too. If you don't want to be confrontational bc you live in her house, make up an excuse of why your LO needs to stay downstairs. Make up an activity that you want to do with your little downstairs... anything. Break the routine of them taking your little one upstairs as soon as you come down. I would never allow any family members to just take my child and go into a room and shut the door. It may be innocent, but it's rude to think that they need to just shut you out. They want to be alone with your child... go for a walk.
