So to cut down the risk of molestation you as parents must sacrifice your own love for your children unless the children ask for it themselves.
As an uncle to a niece and nephew of 2 and 3 and baby sits a lot. I will hug these children every day publicly. My niece isn't a hugable person and when she wants out I will let go, my nephew is a hug machine anyway so I don't even have to ask, he'll charge at me arms open at random lol.
