We are abroad and ds2, aged 3, possibly asthmatic and hospitalised with a pneumococcal infection aged 18 months, has a cold which has turned into a horrible barking croupy cough. No temperature, good appetite, cheerful and bouncy, but I get very anxious about anything possibly involving breathing because of the history. How do I know if/when I need to start working out how to get him to the doctor here, or is the cough in itself OK as long as he's otherwise well and happy? He's coughing in his sleep now.
