After 9 weeks of doctors and hospital it seems that my DD - 10 months - has a chest infection and Asthma. I feel awful I've been on the web - probably a mistake - and the triggers they are talking about make me feel like I'm to blame. We recently had a problem with mould and had to get an extractor fitted as the house was too insulated, we have a cat, I don't know if we have dust mites but we probably do and I'm really not sure what to do or where to start. Does any Mum out there have experience and any practical advice.
