My grandson is 4 1/2 and when we are alone and watching tv, etc. he suddenly pulls up my blouse and kisses my breasts. Last nite he put his hands under my shorts and was feeling my butt. I was so shocked but didn't want to overact in front of him. He is the cutest, loving little boy not an ounce of bad in him. Happy all the time and comes from loving parents. How do I handle this?
