Cooled boiled water

[maize]

Not sure if this is the right place.

Why do you have to use cooled boiled water if you want to give a baby some water or add it to formula to cool it down?

My DH is saying its people being too fussy because water is fine but I think its an important rule.

The thinking is there is bacteria in the tap and water pipes that might harm the baby, maize.

Water itself is fine, in this country, anyway.

you only have to use cool boiled water as a drink up until 6 months though and then tap water is fine
