Ty. I appreciate your response. Your right. We are ignoring it (their behaviour).
Thankfully we haven’t received any nasty texts from them like last time. (Probably cos I gave them a piece of my mind last time so now they think twice)
Anyway hopefully my son has a lovely day with his nan and grandad.
I will add. My partner’s brother has a very severely autistic child who is 4. So I know they don’t have it easy and it must take a toll on them
But they aren’t left out. His parents still see their children.
