Hi mama's, this may seem like a silly question to some but I'm just curious because things have changed since my first daughter was born 8yrs ago.

This is my first time using formula for 7yrs and was wondering if it's safe to use bottled spring water to mix with powdered formula?

I know it says to boil the water but I remember just using bottled water years ago but I also realize standards may have changed. It also now says you cant store a premixed bottle anymore, whereas when I used it last you could store premixed bottles in the fridge for up to 24hrs, but still discarding an unfinished bottle after an hour outside the fridge.

Using boiled right now but was just wondering for convenience sake I suppose lol thanks!
