Any successful eczema solution..?

El

I have a 5m old baby girl who has bad eczema on knees, side of her legs, elbows, belly etc... besides entire skin is soo dry. So far I have tried; applying aveeno, coconut oil, Burt’s Bees ointment and baby oil, virgin olive oil and oatmeal bath and no success... we have 15 different lotions, creams etc and keep applying her full body ointment for at least 3 times a day. We bathe her every night with putting coconut oil on her body and in her tub and let her lie in it for 10 mins... we have humidifier going on day& night...she is scratching her face, belly and knees so badly... we only buy her organic cotton outfits and try not to over dress her and keep house around 72F... I don’t know what else to do but definitely don’t want to use steroid creams. Dr says keep moisturizing but no luck... Does anyone had a similar situation? Do you have any recommendations? 🙏🏼
