Dear Bob if you read my posts i advise caution in useing nappies and plastic pants althoughas there is evidence that it can cause fetish tendantcies in later life which these tendantcies are near impossible to break I would equate it to having a drug and trying to wean yourself off it!However the use in the short term of protection is another matter there is no scientific evidence to suggest that useing nappies and plastic pants on a short term basis causes harm only the prolonged use of them!.I with my chilpersevered with changeing sheets with the one child but with my special needs son because he was not fully aware we went the nappies route until he became aware and stopped! we did not use The D vapp drugas we saw no need for it and are of the mind that use of drugs should be used spareingly! best wishes Tom!
