Hi J.,
A search on Roseola brought up some articles/postings about high temps followed by a rash followed by a return to 'normal'. Maybe try that.
I just posted this list with a mom asking about 'itchy skin'. For the Roseacea possibility and following your hunch: Roseacea is caused by a parasite, demodex folicularium. It feeds on sebum in the dermis layer of the skin where unhealthy cholesterols and fats lie. With your one year old daughter the teething might be the only cause. If your Roseacea diagnosis is on the money it is possible to 'cleanse her system and work on clearing the parasites. Check the list below for common problem ingredients that are in almost all of the things we normal buy/bought.
"That itching has got to be frustrating. My skin got so 'rough' when I shaved. Couple questions to ask: What is in my creams, soaps, personal care products, foods, liquids, cleaning supplies, air, and environments? Is there Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES), Propylene Glycol (PG), Butylene Glycol, Polyethylene Glycol (PEG), Alcohol, Isopropyl (SD-40), DEA (diethanolamine), MEA (Monoethanolamine), TEA (triethanolamine), DMDM Hydantoin, Urea (Imidazolidinyl), FD&C Color Pigments, Fragrances, Mineral Oil, Triclosan, Chlorine (from City water supplies or swimming pools), Heavy Metals, Nicotine, Fluoride, Airborne chemicals from flyover spraying, microwave use of any amount at home or dining out, Aspartame (and all other synthetic sweeteners, Sugar, MSG, Deodorants that contain Aluminums, Cleaners of most types, Air Fresheners...The list is quite intense and scary! It is possible to work at all of these issues. There are some immediate options for your immediate needs. I have access to a lot of information and product options so that we (all of us humans and animals) can live as healthy as possible.
