I just got one but haven’t used it yet. However you can use distilled water you can buy from the store. Distilled water is boiled already.
I’m currently using it and I only use distilled water for it
Thanks for all the comments. I thought the boiling water part was to kill any bacteria in the formula itself not the water?
It'll be fine. Though you do have to wash it after like 4 bottles I heard. And I've never boiled the water for my formula... I've always just used purified sink water (the same water i drink, just warmed) and all 3 of my kids are OK.
