C.B.
My son has allergy induced asthma and eczema. We go to a pediatric allergist. My son is allergic to mostly enviromental things. He showers every night and then is rubbed down in Cera Vu. He takes an Allertec pill nightly and has an emergency inhaler. My daughter has eczema and allergies (no asthma) and we do same routine for her as well. I would really recommend a pediatric allegist (we go twice a year and more if needed). I do know that having children with skin issues we have had to make major lifestyle changes (dye free everything, no perfumes, no scented lotions). I know my son when he was super itchy or suffering badly with his allergies he would not sleep well and he would get super gumpy tantrumy type thing (he is 8 now). You also may need to get a steriod cream for the bad spots.
Good luck to you, i know it is hard.
