So DS 2.10 has had a sore throat for a number of days. He's refusing food this morning but will drink and did manage a little bit of yoghurt. He's got a slight temperature. Ordinarily I wouldn't consider the gp however a child at his nursery has just been diagnosed with mumps. So now I'm concerned DS may have caught it but he hasn't got any swelling (not yet and hopefully won't get it at all) so should I get him checked over today or wait and see how it develops?
