oh gosh this reminds me of something that happemed a few days ago. my mom is hard to shop for and we were in the mall so that she could do christms returns and spend money that some of us gave her instead of actually buying the gift and risking her already having it or wrong color, doesnt fit. we were standing in walmart when this group of kids ranging between 8 and 15 and they all were having the greatest time talking baby babble, little kiddy talk and stand up comedy routines. they were doing this because among them they did have a girl who dispite her teen age years she sounded like a child. dont get me wrong they werent making fun of her. it was their way of helping her to fit in because no matter where she went in the mall every time she would make a purchase the cashiers would ask wheres your mommy dear we cant give you this without your mommy because its for teenagers. So this poor girl because of nature has a child like voice at times and has to go around showing her ID.

I also know someone who is now in her late 30's and still has trouble on the phone having people ask her to "go get your mommy dear and tell her its the electric company"

My neice at 8 thru 15 went through stages where she was constantly talking in different voices. whe she was taken to the doctors to check for any throat vocal cord problems they found out it was just her way of going thru puberty.

I met during school a woman who had told me she went through periods of talking younger than she was. turned out she had polyps on her vocal cords. After surgery she was fine.

the lady who was mary poppins had problems with her voice too which turned out to be not a mental disorder. she had something wrong with her vocal cords. she went thru surgery but for her the surgery made things worse so she had to drop out of her musical career for years. shes just starting to do guest spots now.

As you can see there is no way to know a person has a dissociation problem just by whether they talk like a child at times or not. to find out you will need to contact a psychiatrist and your medical doctor. after they have done all their tests with you they are the ones that can tell you if your talking like a child is a mental disorder or a physical problem.
