Today we found a dead lizard in our main water tank supply. I don't know for how long it has been there. I have a three month old baby and i give him both fm and bm. The water we use to make formula milk first get filter in Kent ro than i also boil it regularly and use it to make fm. Will still be there some poison left in the water ? Now I am worried because of this finding. Till now there is no issue like loose motions or vomiting. Should I be concerned? What can I do now to make sure baby don't get I'll because of this. Yesterday he took a bath and during bath he drinks some water.
