My baby is on a dairy free prescription milk that has to be added to tepid water as the boiling water kills the probiotic. But standard shop bought formula should be added to boiling water and adding it to tepid water could cause stomach upset
No, boiling it isn't to sterilise the water it's to kill any bugs in the formula so the hot water needs to hit the formula.
What you could do is cool a load of boiled water (although I just used cold water straight from the tap as I didn't start formula feeding until 5 months anyway) and add it after you have put a shot of boiling water in with the formula to cool it down once you have killed the bugs.
I used to make 6 bottles up at a time with boiling water. Cooled them quickly in cold water bath in the sink, put in fridge and reheated/used within 12 hours. This time I've just bought a perfect prep machine! They've just bought a new one out so the old style will probably go down in price now.
There has been hype about the pprep machines not getting hot enough.
I've just had my baby and was told they are not recommended.
The formula boxes say to boil kettle and use between 20-30 mins later so water is still above 70°. We just use boiling water then cool bottle quickly under cold tap. They won't say to use boiling water as there have been idiots who have burnt their baby as formula too hot.
The ready made liquid formula is sterile and can be given at room temp. The little bottles are perfect if you are out for the day.
I used to add the formula and 1/3 boiling water and then shake it up and then add 2/3 cold water after 5mins.
I used to make up 6 at a time and then keep them in the fridge but we had prem twins and they were fed every 2 hours and I was pretty unwell after so had to do what helped us cope with it all (save time/trips downstairs).
Sorry AnUtterIdiot but that's absolute rubbish! The instructions for making a bottle say to leave the water no more that 30 minutes because if the water is below 70 degrees it will not kill off any bacteria. There is nothing wrong with making the bottle with freshly boiled water and cooling it. It does not kill the nutrients ffs
The only issue with adding the cooled water to the small amount of boiling water and formula is that the formula expands the volume of the hot liquid so you may not add enough cooled boiled water, iyswim??
