Hi mammas! Just trying to figure out what causes the flare up of eczema with my daughter. The only common threads are heat, a longer car ride, using spf (organic), and hot weather. Could the fabric on the car seat be doing this when mixed with heat and spf??? My daughter has mild eczema but on two different occassions her whole back has flared up and it is not a heat rash b/c it lasts for a couple days...or can heat rash last a couple days? What helps it is hydrocortisone cream. But I would prefer to be proactive rather than reactive. Also, she had a small piece of funnel cake...can that do it?
