Hello all. DD has a horrible cough - mostly at night. She coughs for 20 minutes at a time and it's driving her and us nuts as our sleep is so disturbed. We've taken her to the doctor he said it was 'a self-limiting upper respiratory tract viral infection' and that it might last for 'weeks'. Is there any cough medicine that you'd recommend? Or any other tips? (She's 21 months) Thanks in advance.
