To filter, or not to filter?

[Becks123]

I am in the process of moving my 6mth old dd from breast to bottle and have been filtering all the water for the milk. My friend has just told me that this is not a good thing to do, although others have advised it is. What's the general rule???

I have heard that you are not supposed to filter water for formula - but I have absolutely no idea why not! It certainly isn't necessary - so long as you are boiling it. Hope someone else knows.

I don't think it makes a lot of difference. You're not supposed to use bottled waters as they can be too salty, but filtering takes out impurities, it doesn't add anything.
The only concern might be that it could filter out flouride at a time when the teeth are just strating to develop. In some areas dentists recommedn flouride supplements so you don't want to be depleting that.
Anyway as Marthamoo says, it certainly isn't necessary. Just boil and cool, and don't boil twice.

You're not supposed to give unboiled filtered water to babies because filtering removes the chlorine, so, in theory, bugs could grow in the water.

I wasn't sure what to do abut filtering when making up bottles for my ds, because I don't care for the taste of our tap water and can see the difference in the kettle etc when we only use filtered water for tea and coffee etc (much much less limescale). In the end I used plain tap water, theorising that the formula is probably made for Englihs water, so the amount of minerals in it probably takes into account the typical levels in your average English tap water, so best not to muck about with it. Probably all nonsense anyway, and utterly immaterial!

Interesting! It's a toughey isn't it. Chlorine is so highly toxic that you really want it out of the water - but are the bugs that may grow in it more harmful anyway? Hmmm...

......I guess boiling it takes care of the bug issue. Thanks for the advice!
