The supply of water, that we use, comes from Municipal Corporation. Yes, definitely it is treated water. What I am not sure is how it is treated. Probably, using bleaching powder? If that is how it is done, this could be a source of chlorine!
Do you suggest we stop bathing him for few days and watch? Unfortunately, this is the only source of water at our disposal and we are left with no other option but using it. We think if that is the source of problem, then we need to find out a way to remove the chemicals from the same water.
Yesterday evening, we removed all dry flowers and live plants from our house to eliminate the possibility of existence of any pollen.
We also removed couple of things, like banana and egg, from his diet and monitoring the flare strictly.
