Overreacting?

MIL keeps making remarks about my toddler’s eating and several were accusatory of starvation. This is something she has done since he was born. I have finally gotten to the point where I am sickened by her. We were in my car. My OH was driving, my In-Laws were in the back with my toddler. He likes to chew on one of his toy cars. MIL noticed this and said things along the line of “Are they not feeding you?”, “Poor starved child”, and “Mummy and Daddy don’t feed you so you eat toys”. My OH replied with a blunt “Yep, must be it”. I, on the other hand, glared at him because he knows how much these comments bother me. My toddler gets plenty of meals and snacks throughout the day. I will never deprive him of any food, especially when he asks for something. He was born on the smaller side and is slim. Despite this, he is healthy and active. His Doctors are happy with his eating and have never expressed any concern over his size. At lunch, my toddler was eating a lot of food. She then started to comment on this, too. I put more food onto his plate and then she decided to say that I was barely eating anything. When I said I was full, she scoffed. I have told my OH that the comments from my MIL are unacceptable. I emphasised that as someone who had an eating disorder, I find her to be vile. She often comments on my eating habits and has accused me of starving myself (in front of guests) when I was postpartum. I have also reiterated that I will not allow her to be around our children if she continues with her disgusting behaviours. I do not want my children having eating disorders or thinking there is something wrong with their body image. I, personally, do not feel this is an overreaction. I have already distanced myself from her. My OH is stuck in the middle of respecting my wishes but also having to deal with my MIL playing victim, so I do feel for him.
