I typically have no issue with drinking tap water - the fluoride and minerals don't worry me.  But since becoming pregnant I've been avoiding tap water altogether.  I buy a few gallons of Nestle Pure a week and try pretty hard to use it for all my drinking and cooking.   I'm first trimester, and am concerned with  fluorides neurotoxic properties during this time when baby's nervous system is developing.  Is anyone else concerned with fluoride in their water?
