Special needs son but judgy family.

Hi, so I'm posting anonymously because i have family on glow.

So my son was diagnosed with autism 2 years ago. We kept it within ourselves because getting therapy and helping our son was priority and judgy families werent. With an exception for my side of the family. Recently this year we told my husbands parents, sisters and 2 of his cousins. Well, a lot of my husbands family members don't know our son is autistic. Not because we're embarrassed cus we're not. Last Christmas we got a lot of side eyes and whispers at a family party on my husbands side. So this year my husband won't be with us for xmas because of work (deployment) so I'm soloing the Christmas thing with my in laws and family. My father in law says the dumbest stuff regarding my son, even tho i told him to ask me any questions he has and I'll answer them but he still likes to make the dumb remarks. Which is why we didn't tell the rest. But since a few already know, how do i go about telling the rest of his family like his aunts and uncles, and cousins. My husband has a lot. Is it bad to do that. Last year one of my husbands aunts complained my son was being naughty. 🙄 he had a melt down because there was like 30 people in the house being loud. He actually did pretty well last xmas and we were proud of him. So is it a thing, to do something or hand out something about autism awareness? And how do i tell them? Create like baggies or something? Key chains with an attached note? I have no idea. He's my only kid and i don't want to prioritize the family over him. Hand them out on xmas?? He's come a long way but still has his moments everyday. ♡
