Prep machine temp

[Anonymouslyconercned]

just been testing my prep machine and noticed that the hot shot comes out 72 degrees plus, but because the prep machine tells me to add formula first, when the hot water hits the cold formula it instantly drops to 61 degrees meaning it’s not hot enough to kill the bacteria in formula.. I tried adding the formula to the hot shot instead but the hot shot cools down to 59 degrees before you have time to add the formula and that’s with it being in a formula pot and trying to do it as quickly as poss…
everyonr I know uses a prep machine so don’t know if I’m looking too much into this or whether anyone has experienced the same?
I use mam bottles so really hard to cool down in a bowl of cold water as they have a vacuum bottom which allows water in when submerged apparently, so started using the prep machine as seemed the most convenient but looks like I might have to go back to the old fashioned way I was doing before

The prep machine is not recommended for the reasons you have stated.

I used the rapid cool. Or just did a manual prep machine method - kept a flask of cooled boiled water each day, mixed the formula with few Oz boiling water from the kettle then topped up with the cooled boiled water to get the right temp

Same as @dhxxx really. I ditched the prep machine I just didn’t have a good feeling about it and it made the formula really bubbly and gave my LO terrible wind so now I put formula in first, add boiling water for a hot shot, swirl the formula and top up with cool boiled water I store in sterile bottles in the fridge. Same method when out too but I take a flask of boiling water and bottle of cool boiled from the fridge. So my much better I found!

We used the principle of the
Perfect prep. Dissolved the formula in recently boiled water (less than 30 min) once it was all dissolved top up with cooled boiled water.
For a 5oz bottle we did 5oz formula in 3oz boiled and 2oz cooled water. For 8oz we did 5oz boiled and 3oz cooled
