Not sure if this is a weird one. Ds is 9 months so drinking regular tap water with meals. He's on a cow's milk free formula which says to use room temperature water as it has probiotics in it
We've been using the perfect prep - pressing the button twice then adding powder so the powder doesn't get the 'hot shot'.
Perfect prep is going away now as we're out of filters and it's cluttering up the kitchen. But thinking about it, aren't we essentially just using filtered water? Can't I do that instead of cool boiled water considering Ds is used to tap water anyway?
Personally I don’t see the problem with using the brita water - I think you only have to use the hot water to kill the bacteria in the milk, so if you don’t need to do that then room temp tap water should be fine - filtered is a bonus. At least that’s how I’d see it.
We tended to use boiled water out of habit - so sterilized bottles, filled with boiling water and then lobbed in fridge until required. That way we had a system and it was no extra faff than using tap water.
You don't need to boil the water to kill the bacteria in the water, but to kill it in the formula. If your formula says not to use hot water, then you don't need to worry about it as much. I'm not sure what these specialist formulas do differently, but I suspect they undergo some sort of different processing that makes them less likely to harbour bacteria. But yes, if it doesn't say to use hot water, then I would use tap water as it's not the water you have to worry about.
