Kissing children on the mouth

***I did not say I sexualize children. I wrote, I see kissing on the mouth sexual. In my household no one ever kissed on the mouth and it's reserved for LOVERS! Kissing on the forehead and cheeck is MY personal preference. Just like some of you think my preference is weird, so do I about yours!! There's no need to be rude***

I shudder when I see this, since I refer kissing as a sexual thing. There are adult children who still continue this practice with their parents.

I did see a documentary on this where it discusses at what age should children stop being kissed on the mouth!

Do you prefer this? And do you have an age limit?
