Crazy MIL, need advice!!

I have a justnoMIL, she’s really terrible. Luckily she only visits a few times a year because she lives in another state. This also causes problems though because when she does visit everyone expects her to be able to do whatever she wants, if you don’t let her do whatever she wants she throws a major tantrum, crying, shutting herself in the bathroom, the works, ruining the whole visit. Well no one wants to say anything to her about her behavior and ruin the visit so she just says and does the most wild shit. Yesterday she was visiting, my 2 year old is mostly non verbal, and my MIL has only met him 3 times in his life so she doesn’t know him at all but my husband and I have told her many many times my toddler does not like people grabbing and touching him. Well when she arrived she of course tried to grab and kiss him (probably because we told her not to do this and she’s a fucking huge toddler herself and wants to do what she isn’t supposed to), like literally all over it was like she was trying to make out with his entire body. I said that’s enough after a min but she ignored me. My son HATES to be touched by strangers. She is a stranger to him. She grabbed him and wouldn’t let go, kissed his feet, all kinds of shit and he hates every second of it and I didn’t say anything beyond that’s enough because she was only visiting for a few hours and I didn’t want her to explode on me. Now I feel upset with myself because my toddler was very unhappy and seemed beside himself when the day was over. At first he tried pushing her away and even hitting her but she’s way bigger so she would just grab his arms. Does anyone have advice on how to handle this situation? I want to tell her to back off of him but I don’t want to piss her off and ruin the visit if possible. I’m literally sick thinking about this and thinking about her next visit, I cannot let her do that to him again. via /r/Parenting https://ift.tt/2Xk4t7X
