my DD 3.10yrs, has always been a very clean person (doesn't like having dirt on her clothes - we go through about 3 changes of clothes a day, always washing her hands etc) and has always has a thing about smells. it was really bad at first, where she would constantly get go on and get upset about it, so it would cost me a fortune in air freshener. at one point she started to get a little better, but all of a sudden the problem has returned, so again costing me a fortune in air freshener. if i don't spray room freshener, she gets really upset and sets her asthma off.
Any ideas what this is, and how do i tackle it??
