My 5 month old DS has had a cold for 6 weeks now, even had anti biotics last week which improved it for a couple of days - but back with a vengeance now and we've not even finished them. I've tried everything - nasal drops, vapour rub on chest and feet, elevated cot, infant olbas oil, steamy bathroom etc etc. Does anyone have any other helpful tips/advice? Is a humidifier the answer? Or anything else that might work? He's not got a temperature but as the night goes on, struggles to breathe through his nose more and more and so cant keep his dummy in either!!! HELP!!!!
