That's not what I meant. See below. Gee, thanks Sherlock Fleming. I also voted no. That's not what I meant. Here it goes: The mom is giving the child this somehow.
But... the OP's goal was to give a character a water allergy. I don't think it's really a solution for a different character to have a mental illness that causes her to abuse her daughter by faking the symptoms of an illness that still isn't a water allergy. The OP's goal = child with allergy; your solution = mom with mental illness. They don't really fit...
It is if its munchausen by proxy I normally wouldn't recomend this site for accurate news information, however, I think Buzzfeed sums up this specific case better than any wikipedia or psychology database. Just to show you how you can "fake" a medical condition. https://www.buzzfeednews.com/article/michelledean/dee-dee-wanted-her-daughter-to-be-sick-gypsy-wanted-her-mom
I know what munchausen by proxy is. And, honestly, no, I don't think buzzfeednews is a more reliable source than a psychology database... Can you explain how giving the mother a mental illness will have the same effect on the story as giving the child an impossible allergy?
That's true, but the fact that it is being caused means it can be exaggerated and modified as well. For example, that the child also has issues when drinking water (not what the OP said, sure), so it would confuse doctors and whatever.
If "this" (Aquagenic urticaria) is good enough, the poster can just use that disease. We don't need the mother, Munchausen by proxy, any of that. He can just use Aquagenic urticaria. Done. But the poster wants a water allergy.
Yeah, and that's water allergy. It doesn't have those symptoms, but still. And before you get all worked up about the term "allergy" and start angrily typing all the "Well, if I may say something here, technically this is not an allergy because <insert facts from imright.com here>" posts, let's just stick to this: so while it may not be really an allergy, it's called allergy. I have also been reading the Wikipedia pages for other languages and it says the same thing. Is there any reason why the OP wouldn't want this?
Because it doesn’t fit the symptoms in the OP’s post? And because it’s not a water allergy? If he wants it, he can use it. No mentally ill mother required. But he seems to want an allergy.
Yeah. It's funny that the character would have a crazy reaction when drinking water. What, did this person never drink water before? It doesn't look like the OP is interested at all now anyways.
