AITA for calling out my mIL whenever she tries to give food to my daughter?

So I’ve had my daughter for 5 years and with my wife for 4, she has 2 boys from a previous relationship. My mil is a great cook, however she often tries to give food to my daughter or buys her candy when I specifically say she isn’t allowed. For instance she ordered Chinese food and told me to give any leftovers to my daughter, I told her my daughter doesn’t like Chinese food and that she’s not allowed food after 8pm and my mil said that it’s not like she’s going overboard with the food. I told her that she’s my daughter and I get to decide what she eats, my mil told me I shouldn’t deprive her and that she’s just looking out for her. AITA<br><br>Edit/Update: My daughter just came home from school, my mil and wife both came over and tried to give her cookies and milk but my daughter is sick with a stomach bug and is fasting for the day, I told them she can’t have any and asked my wife to takeaway the cookies. My mil started talking about how even though she’s step mom she tries to think of her as her granddaughter since she doesn’t have a daughter. She went on to say that even though I’m her son she feels like I wronged her intentionally by only having a daughter and said that she’s fulfilled as a grandmother since my wife has 2 boys. I asked her what she meant and she said that I’m so cold towards her and don’t care about her feelings, I’m just a mom away from my daughter. I told her that wasn’t fair and she got up and left. My wife said that she went too far and that she was wrong, my wife is apologizing and then my il called and asked why my mil was crying and he told me I should be more forgiving. I told him it was the other around and she was the one being mean and trying to overstep in my parenting. He said “so this means you don’t want a mom anymore?”
