My whole family thinks my toddler is autistic

My entire family thinks my toddler is autistic and constantly hints at it during conversation and it’s really getting annoying. I’ll start by saying there is NOTHING wrong with being autistic, I have a few family members with autism and they are loved just the same, I just don’t think anyone “wants” their child to be autistic and I feel like it’s rude and not nice to assume things like that about someone else’s kid when you’re not a doctor or a professional. I will also add before I continue that I have already had him evaluated because of this and he does NOT have autism and is not on the spectrum whatsoever. My son is 2 and ever since he was a baby like not even 1 my family members make comments all the time about things he does that makes them think he is autistic or on the spectrum or just has something wrong with him. He has also had a pretty high tolerance for pain, they all think that’s a sign he’s autistic because sometimes he doesn’t cry when he gets hurt. He is pretty emotional at times and does get overwhelmed but that’s just a normal toddler thing ? All toddler go through emotional phases of trying to navigate their feelings and how to express them etc. the other day I was talking to my mom and make a comment about how he’s in the “terrible twos” and how I hate going to the store lately because he throws fits in the buggy and doesn’t like being in the store. She responded by saying “well you know if he has autism or is on the spectrum that’s a sign, he could be overwhelmed in public spaces and that’s why he acts out when you leave the house.” Like no, that’s again just a normal toddler phase. All toddlers have thrown a fit in the store at least once. A few weeks ago I went and visited my aunt and she said something along the lines about him being evaluated and wanted to know if it was “confirmed” that he has autism. I said no I have already told everyone I got him evaluated and he is perfectly fine he does not have autism. Even my bfs mom has hinted at it she’s said things like “you know it runs in your family so he very well could be” it’s just getting ridiculous because nobody says anything like this about any of the other kids in the family, ONLY mine. And I don’t even know why because he is soo smart like idk what he’s doing that they think is “not normal” or “wrong”. It would be one thing if I hadn’t had him evaluated and ruled it out, it would be one thing if he was showing clear signs and I was just ignoring it but I had him evaluated and even seen a behavioral specialist, speech therapist, etc and he has nothing wrong with him. The lady who evaluated him said he was actually very advanced for his age, his speech therapist said the same thing we literally saw the speech therapist ONE time for an hour and she said we didn’t have to come back because he was ahead and did not need their services. The behavioral specialist said everything he is doing is totally normal and appropriate for his age. We do not see any type of therapist or specialist anymore because they ALL said he doesn’t need it. It’s just so annoying that I’ve had autism ruled out months ago and they all CONTINUE to bring it up and hint at it every chance they get. Literally it’s almost every time we’re around a family member something gets said. I shut it down immediately every time but they still have something to say the next time I see them. Every time we visit family I feel weird the whole time and feel like they’re just watching everything my child does or judging him or secretly thinking something about him. It makes me not want to bring him around anyone anymore because the older he gets I don’t want him hearing comments being made like that about himself and making him feel like something is wrong with him or that he is different from the other kids in the family. The older he gets he’s going to remember comments like that and I just don’t want that to happen.
