Making formula with cool water?

[Prusik]

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?

I realise I didn't say what I was going to do! I was thinking of using our Brita filter for bottles instead of cool boiled

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.

That's my logic too. It's not like he's less than six months and drinking boiled water anyway. Thanks

It's the bugs in the milk powder you need to kill, so a splosh from boiled kettle is fine but you still need the heat on the powder first.

specialist formular can have different instructions.
follow the instructions on the box.

Specialist formula (like neutrimigan) has helpful proteins in it that would be denatured by the boiling water. Specific instructions on the box ban boiling water (or water above 50 degrees approx!)

Yeah the instructions say room temperature boiled water. Logic suggests that the boiled water is superfluous now as he drinks tap water at other times?

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.

Where I live (not UK), it's not recommended to give babies filtered tap water as the filters can harbour bacteria. They say ordinary tap water is better.
