Diorreah Since Second Set of Imms

Hi Ladies and Gents,

My DS had his second set of Imms last Thursday and since Sunday he has had a terrible bout of diorreah. They range from slimy and mucous to paler than usual curd not to mention foul smelling. Otherwise, he is well no vomiting etc. I took him to the docs today and he suggested gastrocolic reflex but he was fine until he had the rotavirus vaccine! 

Any experience of this? Sorry for the gross content ha ha.
