Is there a mental condition that might cause someone to want/try to prove that their healthy normal kid has a developmental delay?

I know someone who seems to be convinced that their apparently normal child has some sort of severe developmental issue and keeps talking about regular stages that basically all kids go thru as symptoms of it all the time. Their kid is one year old and the father isn't like this (he's a friend of mine) but his wife is always talking about it. For instance, the kid will babble like a regular one year old and she will start talking about his "speech delay" and she uses terms that people use for kids' delays like "he's completely non-verbal" or he will get excited and dance to music like babies do and she will say, "There he goes again, stimming." If he doesn't like a strange food we offer it's "sensory issues". Obviously I don't have a degree in child development but I have two kids and six younger siblings, as well as nieces and nephews now, and I pretty much know what a one year old usually acts like. And her kid acts like a typical one year old boy. If there were things she was mentioning that we hadn't seen, that would be one thing, but she's pointing out crap that he's actively doing in front of us and labeling it as signs of autism or something.I know it's not really my business but I kind of worry if she seems so bent on having an autistic child, won't that harm him growing up if he's not actually autistic? Or would that be no big deal? And doesn't it seem like there must be something a little off with her to be so strongly wanting him to be affected by some condition? via /r/Parenting https://ift.tt/2xHiP1I
