I saw a programme on TV which suggested a link between children's asthma and, among other things, dustmites.
This gave me the idea of a link between asthma, especially in children, and mums who are too tired and/or busy to do the extra cleaning required. A mum in full time work must find it dificult to do even ordinary housework. I suspect that it would be economical to spend money enabling these mums to work less instead of on all the treatments.
I would like to hear from parents of children with asthma who work, those who do not work, working mums whoes children do not suffer, Non working mums whoes children do/do not suffer.
