DS2 has caught a cold from his brother who has just started reception. Last night DS2 had a terribly barking loud cough, woke up awfully wheezy, was speaking more quietly than normal but settled back down quite quickly. This morning he was wheezy and quiet when he woke up, but got less wheezy and quiet after some Calpol.
If this is just a chest infection/cold that's fine, but could it be asthma? I have never had it so I know nothing about it. DH and his brothers all have asthma but he is abroad at the moment.
Tips, anyone?
