I think when talking to her if the word weird comes up ask her if she likes thinking she’s weird ( using her word) some kids do rejoice in being ‘different’ and it could be that she’s picked up on the word in a positive way, however it could be the reverse so then if she says ‘of course not Nan it’s what the others call me,’ then without using the word autism I d bring into the conversation famous people who have been considered ‘weird’ particularly anyone not too ancient so she can see that she can be famous or successful
When my granddaughter was diagnosed with dyslexia we talked about all the famous people with dyslexia She was afforded help at school but refused it all point blank as she didn’t want to be different to others She’s worked it out for herself and is now successfully studying psychology and criminology at Uni
However I do agree with others that the mum sweeping it under the carpet isn’t helping at all at 12 she will know very clearly that she’s ‘different’ what she does need to know is that ‘different’ can be fantastic
