mommas who bottle feed do you sterilize your water and formula? or just use room temp?

I was told to boil the water for 1 min then let it cool. I make a gallon at a time and use old Arizona tea jugs. I mix 20oz of formula a day and just pour in to bottles and warm as I need it. He also gets 10oz of pumped breast milk for breakfast (in 2 separate servings).

Oh ok thanks for the insight I wasn't sure if it was necessary but my LO started spitting up a lot so I'm trying new things @valrocks

I used the baby water so boiling it wasn't necessary.

@quansmommyy, what I use too. it says on the bottle it isn't sterilized. boiling it has helped with the throw up tremendously
