Wow some great advice here. I'll need to keep this page for myself for future reference.
I was gonna say, like others did, detox the home of many common household cleansers (that's how Soapworks got started: the mom whose baby would get deathly ill amd they couldn't figure it out, then she finally figured out it was always the day after she cleaned the house...so necessity was the mother of invention). Did you know that some astronomically high percentage of all pollutants are found inside the home? Don't remember the exact %, but it is well over 70%. OTher thing I was gonna recommend is a air purifier (not filter) by ____@____.com://www.EcoQuestIntl.com
I researched them awhile back and found them to be the best at the time. They're not cheap though.
My girlfriend was selling them, so if interested, contact her: Elizabeth Kiely ____@____.com
Good luck. I admire how you are trying to approach this holistically.
