My son cries if you even mention going upside down.
My son is 5. Ever since he was about 2 he has never liked going upside down. It use to not be bad (I wouldn't do it all the time just every now and then try to get him to experience it so we would hopefully get over the fear) well now he is 5 and if you even mention going upside down he will tell you no he's gonna cry. I know this isn't a major issue but I was wondering what could cause something like this.
