I've told my MIL on various occasions that I don't want anyone kissing DS. Yesterday went to the extent of telling her "Dad and I don't kiss him either" we did up until DS has developed some sort of oral thrush twice now.
Of course a lot of things could be causing this, doesn't necessarily mean it's kissing him, could be the fact that he's crawling and tries putting everything in his mouth. Regardless, I've always said no one is to kiss his mouth, and she's never respected this, especially now that father and i aren't to do so either.
Yesterday when I told her off for doing so, she said i've got DS in a bad habit of kissing, he kissed her, which is complete trash, he doesn't know how to. He does not kiss.
I've tried teaching him to blow kisses, give me kisses on the cheek and do the same to him but he hadn't learnt it yet, so it's impossible he would've kissed her.
AIBU to tell her if she does it again there will be serious consequences and i'll consider less visits since she can't respect parental boundaries?
