My husband taught my son to kiss on the lips. And son loves me so much so every time he kissed him, boy turned to me and kissed me and reject the dad's kiss. It was harmless really. But then he learnt how to actually hold your face in place to kiss. My mom came over and he did this to her. I havent seen him kiss anyone else but now he actually tries to eat someone's lip (not just using his lip) so you can feel his saliva, tongue and teeth in his kiss. Of course i turn away and give him a the cheek to kiss because am not comfortable with such a kiss. I know he doesn't mean it in any romantic way but now i worry he might do this to strangers and they might not be as understanding. How do i stop this habit? I dont want him to be the 5 year old who goes around kissing all the girls and boys in kindergarten. Sorry if am being paranoid but it is a bad world.
