Father in law (62m)is too touchy with my(32f) 4yo daughter. I need the words and courage to set boundaries.

I have always gotten some weird vibes from my father in law. I've know him for about 8 years now. He is always really touchy, squeezing my shoulders, patting my arms, rubbing my lower back. It creaps me out. I've even caught him staring at my breasts a couple of times. My SIL (26f) says that he is always like that with everyone, even her male friends. He is definitely a self described "very affectionate guy" because his father was never affectionate with him at all and he didn't want his children to feel unloved.Now he seems to be really focused on my 4yo daughter. He pulls her into his lap to play "horsey", tickles her all over, and tells her that she has to give him kisses. While I felt uncomfortable with these behaviors, I kinda wrote it off as being affectionate grandpa stuff, and that I was maybe being overly sensitive, but tonight I feel like he crossed the line.He was tickling her and she specifically told him to stop many times. I should have spoken up to tell him to leave her alone, but instead I just said, "OK, time to go" and picked her up to got to bed. She told me later that he wasn't listening to her and that he didn't like it when she said stop.I'm worried about his behavior and I need the words to diplomatically but firmly set some boundaries. My daughter needs to know I will stick up for her and to learn that it's OK to say no to unwanted touch.TL;DR: Father in law is too affectionate with my daughter and I need help to know how to talk to him about it. via /r/Parenting http://ift.tt/2h4PsRd
