@Imogen I will do that. We’ve had so many conversations about unsolicited kisses and the harm it can do.
If she doesn't listen stop the visits
Honestly don’t let it slide because it sets up the foundation for the rules as he gets older. When my LG is with my MIL she’ll text me things like “oh I just gave her a little bit of juice” or “oh she just had a few extra ounces of milk” knowing I don’t want her having any of those things. So when I’m around her I have to constantly point out how the extra milk doesn’t do her belly any good or how amazing she is with her water so she doesn’t need any other type of drink. If she thinks she can get away with it then she will with all of your other rules x
If she wants to be that ignorant, I would share an article with her where a baby has caught rsv/ herpes and show her exactly why you don’t want people kissing LO. Just say it’s for his safety, and you’re advocating for him.
