I know deep down that I am right and MIL is wrong. But sometimes she makes me question my parenting when she is so adamant that she is right.
So ds is 9 years old, autistic and self harms by biting himself to the point where he leaves bruises that are a very weird shape if you don't know what they are. I try and avoid triggers, and gently stop him and distract him if I see him doing it. Anyway BIL asked him where he got his bruise from and I explained. Cue MIL telling ds that only babies bite themselves and he is being really silly. I then told MIL to stop saying that and we don't say things like that to ds. She then tells me (not for the first time) that I'm not strict enough with him.
