My 1 year old has a horrible croup- like cough. She is fine in herself..bit of runny nose. and during the day has only coughed a few times. Since she went to bed though her breathing sounds awful. Sounds more in her larynx. Im sure its croup. Its exact symptoms from NHS website. Her colour is fine but breathing is so noisy. Its better if i pick her up but she wants to lie down. When do I worry?
