we LOVE Crunchy Clean and Rock'n Green Detergents (both available online, the least expensive option is the company site on both) - discovered these when started cloth dipes many moons ago but they are for clothes too. If you have hard water, Rock'n Green is the best but Crunchy Clean has the best smells! We use wool dryer balls (found almost anywhere: diaperswappers, etsy, etc) instead of fabric softener - softener's not good for your machine or hoses anyway.
We use alot of Eucerin Cream, have a whole house humidifier (inexpensive to have installed by a professional IF your furnace is not on an upper floor), have a UV light installed and a carbon filter - these things are expensive but worth it. take bleach baths as needed (1/4 c. to a tub full of H2O about once a quarter - as your allergist recommends).
This condition is typically exacerbated by dairy and any other food allergies present; my family carries the following: ALL nuts, peanuts, eggs, peas, grapes, shellfish, fish, ginger, garlic, rosemary, potatoes, poultry, maple syrup, ALL peppers, ..... It can also be exacerbated by seasonal and/or environmental allergies including but not limited to: trees, flowers, grass, animals, mold, mites, dust, .....
We eat organic, alot of raw, drink soymilk, and try to where as much organic as possible..... all of these things seem to help. combined, while we're still so allergy-fied going outside can be a scary proposition, We have the best life possible for us and are able to avoid allergy meds as much as possible (my DH and I grew up on multiple allergy meds and find the side effects so detrimental to our quality of life that we only take them/give them to the kids on rare severe occassions).
As an aside, there has been some determination of allergies associated with ADHD, and side effects from the meds include sensory input overload which can result in huge (negative) behavioral changes, including mood disorders.
If your kids have food allergies, visit kidswithfoodallergies.com, peanutfreeplanet.com, FAAN.gov....I know there are others but I'm pressed for time - sorry!
Good luck!
