Ds2 (aged 11, year 7, ehlers danlos syndrome, sensory processing issues and autistic traits) has actually been invited to a party for the first time in about 4 years. I've always stayed at parties in case of meltdowns but he is adamant he doesn't want me to stay this time. I don't know the mum at all although I do have her mobile number from the invite.
Not sure if I should say anything to the mum. Ds2 has had meltdowns at school before so the girl having the party will know he has them. He is quite good at masking most of the time so he will probably make it through the 2 hour party but there is a small chance he won't. He will also probably flap/stim if he gets excited.
I'm worried that if I say something to the mum then she will panic and assume he has the more complex type of asd (like my youngest child who escapes and licks windows).
