If I use tap water, I boil a kettle full, let it cool then pour it in to a juice jug and leave it on the counter. Then I give her bottles at room temp. During the night I usually take a bottle of breast milk to bed cuz it's ok to sit at room temp for a couple of hours. After she's had that bottle, I wash it, fill it with water then bring a full formula dispenser to bed. When she wakes up I add the formula, shake it up and she's good to go lol

My little guy had been useing tap water even in the nicu they said long as it's not well water he will be fine

I used baby water from the store so convenient

I started by using baby water and would use a bottle warmer, but I found that my LO is good with room temperature milk. Every second counts when LO is crying!

I use the baby water to at room temp and so I just mix as needed. I never mix early so I don't have to deal with reheating and once it's mixed unless it's refrigerated it's only good for an hour.

Use baby water from the grocery store. Then you don't have to boil just put it in the bottle and serve.

We use bottled baby water. Since I supplement I mix and make all my bottles breastmilk included (I mix in same bottle) put it in the fridge and just warm them up in the sink as needed.

I use my KEURIG

Boiling the water sterilizes it only, reducing the amount of bad stuff that baby might ingest.

I boil a kettle full of water then bottle it after it cools. We usually use it all within the day and we don't add formula until we use it to eliminate having to warm it after being in the refrigerator.
