LSA telling another parent about DS's diagnosis

[jussi]

Interested in people's opinions on this matter.
DS started at a new school after Easter in Yr 1 due to moving house.He has autism and has a statement for 25 hours which they are honouring.
School are doing relatively good job as long as I keep the teacher on her toes!

1-1 very empathetic and cares for my son, not sure how much work she is actually getting him to do but that's another issue.
Anyhow,my son was invited to a birthday party which I was really happy about so obviously went and I was really proud of my DS and how he joined in appropriately with all the games.
When talking to another mother she mentioned 1-1 had mentioned that my DS had autism.Didnt think much of it there and then but afterwards thought it was actually out of order of her to divulge that information to another parent without my knowledge.

I have nothing against people knowing about my DS's autism,in fact I am very open about it but surely it should be my choice as to when, how and to whom I tell.
I am conscious that my DS is approaching an age where other child may mention his autism to each other without actually understanding what it is and I certainly don't want him hearing about it from classmates as I have thought carefully about when the right time would be.

I haven't mentioned anything to the 1-1 at the moment as tbh I don't want to cause disharmony but I would be interested in other people's opinions.
Thanks

I understand you not wanting to have personal information divulged. How did the information come about? Maybe she was explaining that her job was working to support a child with Autism (or something similarly vague) rather than just gossiping about your son.

I do think YABU though "keeping the teacher on her toes"
yes I know it's not an AIBU thread

Thanks for your reply flumperoo.Am curious why you think ' keeping the teacher on her toes' is unreasonable.Maybe I chose the wrong words.Basically if I keep asking for I formation about my son I am given out and if I remind her of interventions that were discussed at previous meetings,she will suddenly remember and apologise and say ' oh yes we will start that next week'.
Various things were not initiated until I brought it to her attention.
I am a teacher myself so know how 'forgetful' some can be!

Sorry for typos!
