Ds5 is 12, autistic and with the emotional development of a toddler, although he is cognitively able. He's also going through puberty so has those hormones going on too.
Recently if my MIL or FIL tells him off he will tell them they shouldn't be telling him off when I or his dad are there. And to be fair he is right. But mil and fil are moaning that he is being rude to them. Which he technically is.
I don't know what to do about it. Unfortunately inlaws go to our church and are our landlords so we can't go no contact. I've told them repeatedly not to tell him off when me and his dad are present but they say we aren't strict enough with him.
