My dd 11 months has had a barking cough for around 4 days, today she has took a turn for the worse, sleeping lots and off her food and diahorrhea. Took her to gp who said croup but no temp so no antibiotics. He said if she coughed for to long to call an ambulance as it can effect there breathing quickly with croup. Just looking for some advice really, anything to help when she starts coughing and how long do i wait while shes coughing to call an ambulance - Is this necessary?
