Despite making her feelings clear to her husband, she revealed he went behind her back and gave access to his mother.
"I found out today through an inadvertent message she sent to a group chat that was meant for him that she has been monitoring everything from when he comes back from a walk to when he sleeps to when he eats."
And she shared that it wasn't the first time she'd had issues with her mother-in-law over how she's raising her baby. She said she and her husband had turned down his mother's offer to move in to "do all the things I apparently wasn't doing properly and save us money on childcare".
"I thought it was all behind us until I saw that text message today from her to him saying, 'the nanny brought him back from his walk ten minutes ago and now he is sleeping'," she wrote.
"I feel like my trust and privacy is completely violated and I don't know where to go from here."
Reddit users were quick to respond with one calling it "the worst incident of boundary crossing" they have ever seen.
"This by far is one of the worst incidents of boundary crossing from a SO that I have seen, and trust me I've got my own boundary crossing SO. This needs to be addressed ASAP. The thought of her watching you whenever she wants is so un nerving [sic]. You are not over reacting."
Another wrote: "This is beyond crossing the line. He is allowing his mother to surveil you in your own home. Does he honestly think that she just stops watching when the nanny goes home? ..."
Several suggested she change the access password immediately and advised not even her husband should be given the new code.
