Dear betty here is a web site that will help you understand what your child is going through. www.whenkidslovediaper.homestead.com this will help you understand and allow you to make the right choice as what to do. i would recomend that you sit down and ask him about his feeling how long has he wanted this and why be very open and understanding and you will have his trust for a lifetime.the web site i recomened has a lot of very good info and you should read all of it including the surve. if your child dose have this fedish (infantilism) it is of no fault of his own and changes are it will not go away. it has been tested that no adult that has had the strong desire to wear diapers has ever give them up forever.but at this age it may only be a phase.the web site explaines this also. if he dose have this stronge desire and you except it then i would recomend you allow him to understand that he is not the only one out there.there are many web site such as www.dpf.com /infantilism.com for people with this fedish such as my self.the serve that is on the first web site, shows that there can be many beifites to allowing your child to wear diaper if thats what he wants.but there is no proff that this causes any harm to the child. i would sugest that you really lesten to what your child is saying and take it to heart they are only young once and once thats gone it can never return.i had only wish i would have had the guts to tell my partens what i wanted but to this day they still dont know.
