eczema

Hi, my 3 yr old has been suffering from eczema since he was 4 mo. We noticed it first when we moved from a coastal area(not, humid) to a city which is dry and cool.
We were advised by our pediatrician to use Oilatum cream and Oilatum soap and not use any baby powder. We did this for almost 2 yrs but it did not reduce as such. It would flare up sometimes with wounds but not too much out of control so far. He also had daily oil bath (coconut oil) until he was around 2. Recently, around 8-10 months ago, we stopped using oilatum(soap and cream) and use only channa dal powder for bath and apply a mixture of rose water + glycerin in equal measures on his body. Since then, the flaring up has reduced a bit and it seems to be under control most of the time. He does have itching. Right now, he only has it on his next, behind the elbows and knees and on his right ankle. One of the homoeo doctors said it would go away with age.. say around 3 yrs. Is there Anything i can do to eliminate it all together? Thanks
