I was told tap water is good for them so after 3 days of being born in went to sink water

I have always used sink water. I was told unless you have well water or a preemie that is still in its first month or two that water from the sink is fine.

I did with my oldest from day 6-8 of his life that nursery water isnt really a need unless you have well water

@valerie_jean, sink water

What do you mean by regular water? I've been using bottled water for my sons bottles since he was born.
