Any ideas how I can help Dd stop coughing? She's on predmix as well as two other drugs. It's day two on these drugs and yes it's help lessen the severity of the cough but now it's much dryer but she doesn't seem to be able to go long without coughing. She's asleep but coughing at least every 1-2 mins. This is day 5 of her being unwell. Please any ideas?
