My daughter is turning 3 years old, she has a very dry skin since she was born... Lately we have shifted our base where the climate is extremely dry & the water is boring hard water, that's adding to the problem. She constantly itches her arms, legs & sometimes the whole body. There is always a white layer on her skin.... At times she itches so harshly that red rashes come up. I had once consulted a pediatrian she recommended Citaphil. We have tried Citaphil, Venusia cream & lotion, coconut oil, olive oil, vaseline lotion, vaseline petroleum jelly, paraffin with water...& currenlty using hydramost lotion...also used teddy bear soap, citaphil soap, seba med soap...j&j products does'nt suit her at all, himalaya soap.....nothing seems to work... Also her water intake is very low...she never drink more than a sip or two at one go... Please advice....thanking you!
