Just want to start with saying I'm grateful my MIL helps out with DC.
However there's a few issues regarding boundaries.
For instance MIL would go into my underwear drawer and take socks. She wouldn't say anything and I'd spot her with my socks on at a later date. She will use my products and hair tools (not a major issue) but always leaves the stuff out. She will also help herself to my snacks, quite often eating multiple or leaving none of certain things. Seems pretty petty but I have been openly annoyed about this one.
However, one time DP came home & she was watching DC who was napping. He walked in and she was walking around naked. She just laughed this off, but had no reason to be showering or walking about naked.
She has started sleeping over to let me work an extra day, it's just a short term arrangement. She brings pyjamas but will sleep naked, get up and walk around naked (usually in front of us) and take DC in to the bed with her whilst naked.
Since that she's started going in the bath with DC without asking if this is okay...
I'm just wondering if AIBU with being uncomfortable about this?
For some reason, I don't know how to approach this.
