I've been in the process of eliminating unhealthy chemicals and toxins from the products that we use and it just occurred to me (duh!) that the diaper creams I use may need to change. I think I need to keep a zinc oxide cream for when diaper rash flares up but what about when things are ok or just mildly irritated? What do you use? Are ointments with petroleum jelly safe? Is it environmentally friendly? I know I don't want anything with parabens or too many chemical ingredients. I know some of you mamas must be knowledgeable about this. Help!
