yea I saw that and again anyone with or without mental and physical problems of any kind can be acting like a kid. my best friend who is in her 30's sometimes acts like a giddy child in a candy shop or toy store in her its not any disorders she just gets so excited about some things. you ought to see her when shes around the puppies in the pet shop cooing and babbling to them and saying look look oh you got to see this all excited like a kid. I was at my parents and caught my parents neighbors acting like kids over the rose bowl they had on the tube bickering argueing high fiving and sulking/pouting. also acting like a kid and talking like a kid isn't in the dsm for diagnostics for dissociation disorders and its not on and its not a diagnosing factor on the DDIS or the DES or the other one I cant remember the name of at the moment. talking and acting like a kid is just normal for some folks when they get excited, angry or what ever feelings that are really strong in them. heck listen to any parent talking to their child they start talking kiddie talk and acting like a kid to get the kid to do things. its so funny sometimes cause sometimes they forget they are talking to adults and use their sweet kiddie talk voice too. I had this one lady cashier in the store say in a sweet kiddy voice "now honey that is over there in isle 1 you see the one over there?' then she burst out laughing, said she was sorry she just came on her shift after dealing with her 4 yr olds melt down. one of my therapist had me do an assignment of going to a playground and watching kids around my age. it was supposed to show me that I couldn't have been to blame for what happened to me. I got the point but I also saw and heard lots of people adults, kids parents not parents singles and couples playing on, sitting on, using the playground equipment, and many adults talking like kids around each other and the kids.

we cant be sure that this persons talking and acting like a kid is definately a disorder of any kind. all we can do is suggest they see a doctor and a psychiatrist who can do tests that can answer that question.
