She denied it when I lost it and phoned her. The day she was here she looked a bit run down (you know that way when you know you're about to be smacked with a shitty cold) so I told her, politely but firmly, be careful, wash your hands and no kissing please (I'd already made it clear from when he was born any lips go on my baby, my foot goes up the ass of the owner of said mouth). I was in the kitchen making us a cuppa and heard the kissing sounds, looked round and yup 😑told her to stop, which she did - you can imagine the atmosphere after that lol.
Next day she calls sounding like absolute death, to the stage where I actually dropped off a wee bag of goodies to help the cold and cheer her up cause I felt rotten for her. By 9pm that night bubs temp was 38.7 and we were in kids a&e. Can honestly say they were the worst days staring at the oxygen monitor and watching it bounce (I did 10 years in labour ward delivering babies so the machines are normal to me, just not on MY baby). I video called her to show her how bad it was and she went completely denial mode "oh the weather.... maybe you didn't dry him properly after his bath." He's 15 months now and a fucking wrecking ball so he's fine, I still have mental scars after it, and it's the only time I've ever seen his dad cry, ever, he watched while they put the NG tube in (tube that goes down baby's nose into tummy to feed them, I'm kinda numb to that thanks to work) and it's literally rhe only time I've ever seen him break. Told his mum that and she still pleads ignorance. Twats.
We have a 12 week old daughter now too, mil bend over once to kiss her the day I got out the hospital but shit herself when I stood up and said no remember rhe last time I asked you not to do that.
Please be firm, that's your baby its your rules or get the fuck out my house. Obviously my case was unlucky/extreme, but it shows how it CAN go. Maybe tell your friend "oh a lass off the forum was falling about her wee boy..." and tell her our story, might be the jolt she needs to understand?.... though again, your baby - she should respect your choices regardless, some folk just need a bit more of a boot upthe arse.
