Is it a known thing that you don't kiss babies on the lips because of germs? I mean, if you have to wash your hands before touching the newborn baby, why in the world would you kiss them?? Personally I've never done it with my niece and nephews when they were born, but some people kiss on the lips to show love/affection like some of my husband's family. Now I'm nervous about people doing it to my son when he's born. Has anyone else thought about this?
