My little man of 3.5 yrs has been poorly with a bad cold and sore throat. He is fine when given calpol, but with nurofen (also tried calrofen, and sainsburys version) he starts to cry and says it stings his mouth. Now he Refuses to have any. Anyone else come across this? It's worrying me as he has a high temp and needs calpol and ibruprofen ideally.
