Anonymous wrote:As a mom of a kid with ASD I've been in the situation in which I can see signs of ASD in a toddler and know the parents don't know. It's hard. You know the child isn't getting help and see the parents getting frustrated. But it's a journey everyone takes on their own and what that friend is doing isn't helping you or your child.
If you like her except for this issue, I would try something like "Susie, I appreciate you want to help Ethan. But it upsets me to have you bring this up all the time and being upset makes it hard for me to deal. I'll turn to you when I have questions or need help finding doctors, but until I do, I don't want to to talk about it. Let's focus on playgroup right now."
This makes it sound as though Op is in denial and isn't ready to "deal" with what is going on with her child. Op has said nothing of the kind.
Op has had her child evaluated by a professional, she does not think that her child has autism and she really does not want to discuss this with the other mother.
If anything, Op could say "Sally, thanks for your concern but I assure you that Johnny has already had a professional evaluation and I think we're good." If she persists, smile get up and leave.
