Can anyone tell me if I'm doing this correctly. My DD is 8 weeks and formula fed. she takes 6oz bottles but is very impatient waiting on the kettle to boil and cool for a feed. We were wasting too much having premade bottles cooled in the fridge.

Someone suggested 2oz of cooled boiled water in a Steralised bottle in the fridge topping up with 4oz boiling water from the kettle and adding the powder and it should be almost at the right temperature.

Would this work to safely Steralise the formula?

Also how long should cool boiled water be stored in the fridge before it's discarded for fresh.

The guidelines seem to change repeatedly for ff but we found making up the day's bottles with boiled water then just adding formula as the feed time came round we had no bother. No need for the fridge as only had water in the bottles. Ds1 would have a few seconds in the microwave to take the edge off and ds2 never had his warmed.

No because water has to be above 70 degrees to kill the bacteria in the powdered milk.

Just make a couple of bottles up at a time and store in back of fridge and warm in jug of water. When you use last one, make another couple. But no more than 24hrs worth.

So pp wouldn't work either...

Obviously this is only if you want to follow current guidelines.

As I understand it it's the milk powder that needs boiling water added to kill any bugs in it. The milk is more of a risk than the water. So I reckon you could make it with half measure boiling water first then top up to the correct mixturewith cool boiled. But I have never done it so don't know if that would work practically.

I wish I could carry on making fresh each time but all hell breaks lose when we have the wait to cool it down. And I actually burnt my wrist checking it before it cooled enough last night confused

I think purchasing a perfect prep machine is the way forward as I don't want to do anything that could cause her sickness.

Could you not do powder, dissolve in boiling water then top up with cold?

This^ It just needs a slosh of 70deg+ to sterilse the powder and then make up the quantity with cold.

Yes I could do that. So measure say 3oz hot water from kettle into bottle pop in 6 scoops and shake then add say 3oz cooled boiled water from a bottle stored in the fridge?

Do it the other way around, I bought two spare bottles and used them solely for cooled boiled water that I stored in the fridge to make it extra cold. I then put one ounce of boiling water in a bottle, added the formula and shook it a bit, then add the cool boiled water, shake again and voila.
Meets the guidelines and basically does everything the perfect overpriced prep machine does.
Or you could store the cooled boiled water in a thermos.

The powder distils the water so you need to make sure you measure out exactly 3oz extra into a spare bottle and not just make it up to 6oz

I have the tommee tippee prefect prep and I think it's amazing.I didn't want a screaming baby at 3 in the morning. we used pre made formula for the first few days and then went and bought the perfect prep, managed to get a really good deal on it. best money I've spent. Takes all the hassle and stress out of making bottles up
