Baby water

Dalon

FTM I’m planning on breastfeeding however I want to prepare for formula as well. I know they have baby water in a gallon but what’s some good bottled water I can use for bottles ? That will make it more convenient for me to grab and go if needed. I want to stock up on it now. I am 36 weeks. Lol when I ask my family this question there where confused but I mean like a 24 pack of water.
