Re: Giving water to babies / water for bottles ?'s
we start around 8 months with just sips from my cup, no special amount each day or anything.
Breastmilk and Formula has enough water in it for baby, so that they don't need extra water until they are 1 but if you want to do sips after 6 months it won't hurt.
I just use tap water but filtered would be fine too, just make sure you don't use a floride free water, because baby need floride for those teeth.
