DS1 has had a chesty cough for a while now - was hoping it would clear up itself but it hasn't. Went to Boots to see if they had any cough medicine and got told there was no medicine for a chesty cough until they are 6 years old 
I don't think it is bad enough to go to the doctors but what else can I do?? It is particularly bad at night so have propped up his pillows, rubbed vapour rub onto his chest.
