my son is 4 going on 5 he is dry but constantly dirty the doctor keeps telling me its constipation and overflow.so i had him privately tested for an intolerance it turns out that he has an intolerance to dairy but my doctor still wouldnt accept that there could be another problem he is still dirty but not as bad as he was and finally a locum has sent a letter for a referal to our local hospital its taken 2 and a half years!!! has anybody else had this problem?
