Do I have to boil room temperature bottle water for powder formula?

I still do bc sometimes it may have a little chill to it

I don't I just use it at room temperature. I have been for 9 months.

nope. I just use room temp

You don't have to boil the actual water you can use hot water from the tap make the bottle & let it sit in there till the milk is warm if you want your bby to have warm milk if not you can use room temp water

You can buy nursery water from the grocery store. For the big gallon size bottle it's 99 cents
