I'm mom too and three keeps my hands always full, especially with my 7 year old asthmatic! Actually, for about a year now, my hands are less full because she is no longer gasping!
You asked what helps you breathe easier and I want to share our success with our daughter because I believe others too can benefit from this all natural approach to asthma control...
Instead of using her drug inhaler, she now puffs on a salt pipe two times a day for 10 minutes each. It is based on the ancient but awesome practice of halotherapy, otherwise known as salt therapy. The use of pure salt for health related problems is well documented. Nowadays, it is used throughout hospitals for acute lung problems and even used widely by cystic fibrosis patients via hypertonic saline treatments.

I hope this helps and that you can find hope in halotherapy the same way we have...
