Hi my almost 1 year old (He s 1 in 2 weeks time) has had a severely congested nose, running constantly with bright yellow/green mucus for almost 6 weeks now. Had him to doctor about 5 weeks ago who prescribed antibiotics for upper respiratory infection (didn t really make much difference if I m honest), took him back to doctor yesterday who said he had double ear infection and prescribed more antibiotics for this. However, he said that he thought his nose congestion/mucus was most likely due to an allergy. I didn t think at the time but I m now wondering if I could try piriton syrup to see if it helps his nose if it is an allergy? I noticed it said not suitable for under 1 but since he s almost one and large for his age (29lb) I wondered if I could try him with some?
