ds seemed to have been getting better, but has now taken a turn for the worse...coughing sounds like he'll choke and is v frequent (drier than before) and stopping him from sleeping. i'm using olbas oil in hot water, and karvol vaporiser...tried giving him sips of water last night, but he didn't seem to really want them...is there a food or drink that i could give him that would help with what is, is suspect a really irritating tickly dry cough? homeopathic remedy is in the post but until tomorrow any tips??? thought it was worth a try...
