Hi, My dd (4 yrs) has been night coughing for a long time and finally we saw the gp last week who said it could be Asthma. He prescribed Ventolin Syrup and said to try it before bed and in the morning for a week to see if it helps. She hasn't coughed at all since taking it so I guess it must be Asthma then. So, now I was thinking about changing her bedding. She currently has down pillow and duvet. Can anyone recommend good anti-allergy bedding or offer any advice? Thank you
