Can I prepare bottles of boiling water in advance for formula?

[Jojonewmaman]

I have just started mixed feeding, expressing some feeds and using formula. I know the advice is very much to prepare bottles as required however I have read that some parents have pre prepared bottles of boiling water, then quickly cooled and stored them in the fridge and added formula when required. Is this safe? And does the powder mix as well in cold water? TIA

Coupled with the tiredness that comes from having a newborn...making up formula during the night with a low light on. I can see the risk, tbh.

toomuch they are nearly ten - I’m sure it did say it then, I just don’t remember! I do know i read the back of the boxes. I know that my assumption was that the potential problem was the water.

This is from a WHO leaflet:

What if I do not
have access to
boiling water?
The safest way to prepare a feed is using water that has been boiled
and cooled to no less than 70ºC.
• If you do not have access to boiling water, you may wish to use sterile
liquid infant formula.
• Alternatively, you can prepare feeds using fresh, safe water at room
temperature and consume immediately.
• Feeds prepared with water cooler than 70ºC should not be stored
for use later.
• Throw away any left-over feed after two hours.

However the same leaflet also states formula is not sterile so a bit of a contradiction.

It's not a contradiction at all, because it's not about eliminating all possible contamination, but about keeping it at a safe level. Tiny amounts of bacteria can be fought off, even by a newborn baby.

So if you make it with hot water it's able to be kept for longer. Whereas a feed made with cool water will be reaching a dangerous level much faster and hence should be used immediately.

Get a tommee tippee prep machine makes perfect temp bottle in 2 minutes I got mine second hand for 20 pounds off Facebook market place loads of them about

@Firsttimemum892 this is a thread generally about making bottles safely not the perfect temperature. Perfect prep does not follow the safety guidelines. You may as well use a hot shot of water and top up with filtered water. Unless you use previously boiled water to fill the perfect prep which most people don’t do.

So if I filled the Perfect Prep machine with cooled boiled water, would that make it safe to use?

I imagine that would be closer to the guidelines @sabulos however you would be pouring boiled water into a non-sterile tank and I’m unsure how often the water is fully cleared through? Is it fresh daily?
The paediatrician my son was under was appalled by the machines, they are just for convenience and people assume because they are on the market they are safe. When actually no filter ‘super’ or otherwise replaces boiling water to mix bottles.
I guess it’s just how much each individual is concerned about guidelines and why they are in place. The majority of infants will be fine.

Thanks. My husband really wants one, but I am unsure about it.

Australian guidelines are from the infant nutrition council which is the peak body of formula manufacturers in Australia and New Zealand. It is outrageous that HMNRC took thier information rather than WHO. Particularly given the remoteness of some communities and the high number of ear infection and gasto in remote communities.
