2 year old DS has been unwell for the past few days. Feeling warm, coughing, runny nose etc. He’s also been rubbing the top and the back of his head and moaning when doing it (he’s non verbal so I can’t ask him why) and he’s slavering which is unusual for him. I’m wondering if the head rubbing and slavering have anything to do with the cold. I’ve checked his head for any spots but can’t see anything
