Author Amilya Antonetti's son, David, spent almost half of the first year of his life in and out of the emergency room. After the doctor's efforts to pinpoint the cause of his distress were fruitless, a determined Amilya eventually discovered an unmistakable pattern: Her son became violently ill about two hours after she finished cleaning house. David was having severe, though not uncommon, allergic reactions to ordinary household cleaners. Amilya's attention immediately turned to finding safer yet still effective ways to keep a clean house -- without putting David in the hospital -- which she built into a successful line of natural products.
