A study conducted in China found that a number of environmental factors could influence the development of eczema in children. On that list are:

New furniture and furnishings
Mold or dampness in mom's home before and during pregnancy, and during baby’s first year of life
Air conditioning
Keeping windows open while sleeping
Pest exposure (cockroaches, flies, mosquitoes) in the home and during baby’s first year of life
Pets and flowering plants in the home
Passive smoking in the home currently, during baby's first year of life, and during mom's pregnancy
Frequency of cleaning

I find that while we are working on addressing internal imbalances at the root of the problem, environmental triggers continue to throw fuel on the fire.

It makes it really hard to put it out.

The good news is that we can make changes to prevent or limit exposures. What do you think? Could any of these be triggers for your child's rash flares?
