My 20 month old has had horrid tummy bug with vommitting and two instants of diarorhea over four days. I am hoping we are over the last of it having had no more vommitting since sunday night (having said that he had not been sick since the saturday morning). Any road horrid enough as that is what is worrying me is that tonight having had unpleasant watery poo i have found that his nappy has two faint orange small stains in the urine area. Is this a sign of dehydration? He has been pretty good with his fluids up until today when he has been reluctant if not admamant not to drink so much. I have to admit to being worried.. how worried should I be?
