DS is 2 and DN (SIL’s daughter) is 14. When DS was born we made it very clear he wasn’t to be kissed on the face. This was listened to but over time has slipped so they would kiss him on the cheek. He’s a very affectionate boy so he decided that he wanted to kiss me and DH on the lips. I’d always kissed him on his cheek but he obviously sees DH and I peck on the lips when we say goodbye to each other. However, recently DN and SIL have been kissing him on the lips to say goodbye. I was thrown at first then just told myself I was being overly sensitive.
Last week, MIL was looking after DS at our house and DN posted a video on her social media of her with DS in his bedroom where she’d gone to get him up from his nap, and she pecks him on the lips in the video. I felt really uncomfortable but hadn’t said anything. I brought it up with DH today and he pulled a face indicating he thought it was a bit odd but then said it wasn’t anything to worry about and DS would naturally stop kissing them on the lips when he got a bit older.
DN also has a boyfriend and I explained that even just from a health point of view I wasn’t happy, because I don’t know the boy but do know that cold sores are easily spread and are a lifelong issues once contracted.
To add, due to childhood SA my internal warning system can be a bit skewed. It’s good in that I notice things other people may not, but I also can’t always differentiate between something totally innocent and something I should be worried about. For example I didn’t think I should ever kiss my own child on the mouth and was really shocked and uncomfortable the first time DS did it to me. But then I got some trusted advice and realised if I pushed him away and made him feel bad for it, that could be just as harmful.
I have a really good relationship with SIL and she and DN adore DS. Also, MIL has respected what we said right at the beginning and turns her head when DS kisses her goodbye so he gets her cheek. I just don’t want to cause a problem if it’s me being overly sensitive.
YABU - it’s fine for cousins/aunts to kiss on the mouth
YANBU - you need to speak to them and ask them to stop kissing him on the mouth
