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

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

Don't use the fridge door, the rest is okay.
In fact does the food standards agency not say that storing in fridge for not more than 24 hours is okay, not optimum but okay?

ismiseeire · 02/04/2021 15:38

Always did this.

Horsemad · 02/04/2021 15:39

I thought the coldest part of the fridge is the fridge door? 🤔

OverTheRainbow88 · 02/04/2021 15:39

Yup. Make 24 hours worth, cool quickly, back of fridge for 24 hours.

Once a bottle of formula is made up it’s supposed to be used within 2 hours. I make my bottles up in the morning with boiling water up to 4/5oz & let them cool & when he needs a bottle top up with boiling water to 6oz & then add the formula so the formula is still getting boiling water to break down the bacteria but it doesn’t take forever to cool down as I have a very impatient baby! I suppose it’s the same way a bottle prep machine works.

Is it the back of the fridge?

Scroll down to the heading " What if I need to transport a made-up feed?"

LaBellina · 02/04/2021 15:41

I did this too.
As long as you surely use it within the 24 hour time frame it should be ok I think.

ivfbeenbusy · 02/04/2021 15:41

The instructions all state you shouldn't do this.....in fact they say dispose after 2 hours Max

I think making 24 hours up in advance is a bit..... much.....fair enough making one up for a night feed so at most it's a 2-4 hours but why do you need a whole day? If you are going out buy the bottles of ready to pour. Opened bottles of that can stay in fridge up to 48 hours

FlyingBurrito · 02/04/2021 15:42

I always used to do this, no I'll effects were ever suffered. In fact I always gave milk at room temp.

I should say though that I ebf until 6 months so dont know about younger babies

TrinityWaves · 02/04/2021 15:42

Yeah I always did this, I didn't even know you weren't supposed to. I'd make them up every evening to cover the next 24h.

FlibbertyGiblets · 02/04/2021 15:42

No because of constant opening, the temp fluctuates in the fridge door area iirc. Make a sense to me.
ivfbeenbusy · 02/04/2021 15:43

Also I have 3 month old twins and it really doesn't take long to cool the bottles if it's stood in a bowl of cold water ....I roughly know when to expect a feed so make them about 30mins in advance ready 🤷‍♀️

It's so they are in the fridge ready to go. I can heat it up in a bottle warmer which takes 5 mins. If I make it up as I go then I have to boil the kettle, prepare then cool it which takes forever. Or at least it feels like forever when she's crying cause I'm taking too long 😬

The powder needs to go into boiling water, if you are adding 2oz of boiling water into cold water then adding the powder you are not killing the germs. A perfect prep sends out a hot shot to kill the germs in the formula, then tops up with cooler water.

Making up formula, quickly cooling, then storing in the fridge is fine as long as the water was hot when the bottles were made to kill any bacteria in the formula, and the bottles are stored in the coldest part of the fridge.

Figgygal · 02/04/2021 15:45

Always did this with my 2
Never had a problem

TestingTestingWonTooFree · 02/04/2021 15:46

It’s more convenient but not as safe. Unlikely to harm your baby, given that this was the standard method not so long ago. You could DIY a perfect prep by making up formula with half recently boiled water, then topping up with cooked boiled water so it’s not so hot.

ismiseeire · 02/04/2021 15:49

It's a dairy product. The risk of making up a bottle earlier is that if the bottles have not been cleaned and sterilised properly, bacteria can develop in the milk.
Clean, sterilised bottles with milk made up for the ensuing 24 hours is so low risk as to be almost negligible.

It's the difference between doing up bottles a few times a day, or just doing them all at once.
Anything for an easier life.

Newmama29 · 02/04/2021 15:49

You actually have to dispose of bottles of formula that are made up after 2 hours, it states on the box & is the advice from NHS. I probably more likely do half a bottle of cooled boiled water & half boiled at the time of needing the bottle so the formula is going into hot water, 70 degrees kills bacteria in the formula.

ShyTown · 02/04/2021 15:51

It would be much easier to use a perfect prep machine since it’s quicker than warming a pre-made bottle from the fridge. But if I wasn’t going to use one for some reason then yes I’d do as you described. Good on anyone that’s managed it but I don’t know how I’d manage to follow the guidelines to the letter. It just doesn’t seem practical to do a fresh bottle using hot water for every single feed especially when they’re not yet in a predictable routine.

ismiseeire · 02/04/2021 15:52

YouCantBeSadHoldingACupcake Utterly incorrect. You don't make a bottle up with boiling water lol. You cool it a bit, then make the bottle up. The sterilisation comes from cleaning and sterilising the bottles!

Chunkymonkey123 · 02/04/2021 15:52

Yes not a problem. The nhs says you can store in the fridge for 24hours.

ismiseeire · 02/04/2021 15:53

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

NHS website actually says if you keep a bottle of made up formula in the fridge, it has to be used within 24 hours. A bottle of made up formula kept at room temperature has to be used within 2 hours. Formula box says to discard ‘unfinished feeds’ within 2 hours, meaning bottles that have been started and not finished or bottles that have been left out.
NameChange74567 · 02/04/2021 15:55

I done this will all 3 of my DC, just don't keep the bottle in the door.
