Looking on opinions on what you would do. My partners mum has been told multiple times no kissing the babies. There's been a lot of falling out over this and other things with her manipulating my partner by trying to get her own way. The girls are 5 months (4 corrected). I don't want kissing with them being young this time of year with rsv and the flu around. She came over in the week after having a massive falling out over the weekend (over text with my partner) he said he would let the dust settle for a while and for once he was actually taking my side and supporting me. Then she came over because she wanted to 3 days later....she then starts kissing the babies feet. She knows we've said NO kissing whether it be anywhere on the body! I told my partner she's still crossing boundaries and his reply was "It was only the feet". Yes but once she thinks she can get away with one thing, it'll be the face again next. My family dont kiss them anywhere as I've asked them not to. I've had enough of all the arguments and her not taking me seriously. She knows I have postpartum/health anxiety and social anxiety so dont like conflict. What would you do in this situation? I feel like she's only going to get worse if she can get away with small things. I feel backed in a corner with it all, like I have no control on protecting my babies and like I have a constant black cloud over my head.
