Hi, my 2 year old has PDA and recently has been coughing every night ALL night. She doesn't cough at all in the day. This has been going on since just after Xmas. Is this to with PDA as I know they said she will suffer from shortness of breathe or maybe asthma? I don't want to take her to the doctors just for them to fob me off again saying "it's just a cold".
