To make formula up in advance and store it in the fridge?

[novaissuper]

Stores in the fridge for no more than 24 hours and heated up with a bottle warmer. What do you think?

I didn't hear them up in a bottle warmer though, just gave them the cold milk from the fridge.

Use Quickly or Store Safely
Prepared infant formula can spoil if it is left out at room temperature.
Use prepared infant formula within 2 hours of preparation and within one hour from when feeding begins.
If you do not start to use the prepared infant formula within 2 hours, immediately store the bottle in the fridge and use it within 24 hours.

I can't believe that people think that they are 'sterilising' the milk with boiling water each time they make up a bottle!

That's exactly what you're doing. Formula isn't sterile and a sterile bottle doesn't kill any bacteria that's in the formula.

The new way of adding it to cooled boiled water makes no sense.

@ismiseeire but formula isn’t sterile, so I thought the point was that you need to use water over 70 degrees to kill the bacteria in the formula, so you are sterilising the milk?

Always done this for both my dc.

I was advised by Midwife not to do this, and I think it says on Aptamil box that made up formula needs to be discarded 2 /4 ? hours after being made. Not sure about other formula brands.

Ah, cross post with @gamerchick!

The bottles should be sterilised in advance of making anything up, but the formula isn't sterile so that's why you need the boiling water to kill any nasties.. correct? 🧐

I used to do this. Not in the door as pp have said.

It was officially “allowed” in the instructions until about 13 years ago!

A freshly made-up bottle can last for 2 hours at room temp after having been made.
However, you can make up the bottles and store them in the fridge for up to 24 hours.

Well, they are destroying bacteria using very hot water but of course it shouldn’t be boiling.

Opened formula isn’t sterile so the hot water kills the germs which I can understand some calling ‘sterilising’.

Incorrect.

Yep you're right @FlibbertyGiblets. 🙂

@ismiseeire
Then please enlighten me?

The 'nasties' only come out when the powder is mixed with water into a milk form. Boiling water is NOT recommended. It's cooled boiled water - maybe 80 degrees, not boiling.

Goodness me. Unbelievable to read this.

"How to prepare Aptamil First Infant Milk

The preparation instructions for our new formulation have changed slightly. We recognise we need to do everything we can to make the new preparation process as easy to follow as possible.
Our instructions have been designed to ensure our products are prepared safely. See our step-by-step guides and bottle-feeding articles for further assistance.

Make up each feed as required

For hygiene reasons, do not store made up feeds and discard unfinished feeds as soon as possible, always within 2 hours
Do not heat feeds in a microwave, hot spots may occur and cause scalding
Never add extra scoops or anything else to your baby’s feedNever leave your baby alone during feeding

"

I would follow the guidance on your formula box.

What you need to sterilise is the bottle and teethes - not the powder.

I can't believe that nobody knows this??

@Merryoldgoat
Sorry, why shouldn't it be boiling? I prepare the feed with freshly boiled water before putting in the fridge, is that ok?

I use perfect prep machine at home as it's so handy. If we're out and about we either use bottles of premade formula or bring a flask of boiling water and bottle of cold water to mix as we need them.
Could you use a flask to have hot water on standby for during the day

Yanbu to risk this if you have a newborn. If they get an upset tummy they can dehydrate very fast.

Arg...meant yabu

Have prepped the bottles for 24 hours daily. My dc have never had a dicky tummy.

Oh yeah, all bottles are sterilised prior to making up formula. The adding boiling water to the powder is an extra thing I do to help kill anything in the powder as it's not sterile.

I made feeds up for the day stood them in cold water to cool quickly shoved them in the fridge and warmed as and when needed them.
Dc2-got a perfect prep machine.
