One thing we've started doing is having the air quality in our home tested and, if need be, cleaned. It's helped so much with my childrens' allergies and asthma. They don't get those headaches anymore and my son is able to sleep through the night! We've been using a company called Decon Pro Green, you can find them online. Improving the air quality is a great idea, it'll do wonders for your living condition.
