I found this fic awhile ago, and it is on fanfiction.net. In it JJ and Emily are turned into kids, but I'm not sure if anyone else is. I didn't read the whole thing, but a part I remember is that Emily was sick and she was in Hotch's office. I just skimmed through it because I was looking for something else. If anyone can tell me what it is, or any fics that are similar, it would be a big help. THANKS!!
