LIVID! MIL RANT

Sorry guys, I have to vent and just don’t have anybody to talk to. So today we had Thanksgiving lunch at my inlaws, we finished the main course and everyone was just sitting around in the living room eating pumpkin pie. Something got into my eye so I decided to check it out in the washroom, for some reason half way to the washroom, whatever was in my eye magically disappeared. So I turned around to go back to where I was sitting, I caught my MIL shoving a tablespoon full of whipped cream into my LO’s mouth! (all of this before she was even 4 months old) I just tapped her back and said ‘Hey, I saw that’ and then I told my husband and right away he said it’s time to go home. My husband and I have strict food rules for my LO right now (no added sugar, no processed foods) and my MIL is aware of that. She’s done this before, She’s smeared cream cheese icing, ice cream, mustard, ketchup on LOs mouth. The previous incidents she was quick, and she was warned that she will never be left alone with her. This last incident she did it behind our back. I’m fuming, she’s supposed to watch her when I go back to work but I changed my mind and will be sending her to daycare.
