What ratio of boiled water to cooled boiled water do you use to make your bottles the right temp?

[nobodysfool]

Thats it really.
Ds is having 3oz bottles at moment and i thought i would ask you ladies before i waste a tin of formula experimenting.
Thank you.

I know it's a dull question but.......

doesn't it involve leaving to cool or something? sorry, no clue but didn't want you left unanswered

you need to mix the formula with the boiled water, as the point is that the bacteria in the formula need killing. formula is not sterile.

so you make up the formula, then let it cool. You can cool it in a jug of cold water.

Thanks morocco.
The latest 'idea' is to add boiling water to the powder to kill the bacteria then top up with cooled boiled water to get it to the right feeding temp.
I just have visions of 20 bottles down the road finding the right ratio.
Just being lazy is suppose and hoping somebody can tell me

The water needs to be a minimum of 60 - 70 degrees in order to kill off any bugs that may be in the formula so you'd be better off experimenting with just the water first, so you can get it that temp.

Once the powder is mixed you can then cool it quickly by sticking it in a bowl of cold water until it's okay for him to drink.

can't you make a feed in advance with boiled water, cool it down and store i in fridge then reheat in hot water to warm up so you're not havinng to make a feed from scratch with a wailing baby

Oh sorry, x-posts there. I'd still experiment with plain water first, then you can add the powder once you've worked it out.

Olihan-Doh of course......dodgy hormones and mushy brain...check.

yousaidit, the advice has been not to do that for quite a while now - something to do with bacteria growth in stored milk.

If nobodysfool does it the way she is planning (provided she gets the ratios right ) then she has a 'safe' bottle at drinkable temperature straightaway..

yosaidit, you're no longer supposed to do that. you are supposed to use the stuff within the hour.also, the warming up bit would really make it a breeding ground for nasties.

olihan we should stop xposting this way

I must say nobodysfool I see nothing wrong with your approach as long as you let the hot water do its job for a few minutes first.

I was under the impression that if the very hot water made contact with the powder it will kill any nasties and topping it up with the cooled boiled water was just the quickest way to get it ready to drink.

That's right afaik, nobodysfool. Your way sounds spot on.

LOL madmouse, great minds and all that .

ooooh, so if dc2 is on night feeds of formula, what's best way to have night feeds ready for when wakes up yowling?

I'm not an expert ysi - but maybe bring a flask of boiled water to bed with you so you can make up the feed and then cool it as the others have suggested?

nobodysfool - I've used that method today and did 2.5oz cooled, 4.5oz boiling. Don't know what the optimum mix is though. Maybe a silly question but does anyone know where you could get a thermometer to check?

I have a food probe I use

I make sure the boiled water(half the amount needed) is 70 degrees - mix the formula in shaking very well then add half fridge temp water (Boiled, cooled then refrigerated)

Seems OK for most babies I feed tempwise

yousaidit, once you know what ratio you need of boiling water to cooled water then either keep a kettle or flask upstairs, when the baby wakes pour the boiling water in, add the powder, shake then add the cooled water to the right quantity. It's probably quicker than warming a cold bottle too.

katymac where did you get the food probe?

Apparently ideally you shouldn't use boiling water as it 'denatures the proteins strings'

Ok its a while since I have done this, but I used to use 3 oz boiling (I did used to run it under the cold tap a few seconds, because otherwise the formula tends to stick to the scoop, because of the steam fro the water) to 4 oz of cooled boiled water, that seemed to make it the right temp for dd to drink straight away. So if you ds is having 3 oz formula, i guess try 1 oz boiling water : 2oz cooled.

For night time feeds i used boiling water in a flask, and had a bottle of cooled boiled water next to the bed, with the formula in a premeasured container.

Good luck!

Not sure for 3oz feeds. For 7oz feeds we use - 3oz boiling water & 4 oz cold water (tap as baby is 10mths). Perhaps try 1 oz boiling with 2 oz cooled boiled water( kept in fridge) and then test temp.

The advice on bottlefeeding and storing feeds is here.

If you were to put a measured amount of boiling water into a bottle, then add power, then top it up to the total volue of water you were originally expecting to use then you will end up with the wrong concentration of formula. This is potentially dangerous. When the powder is added to the water the volume increases, so you cannot accurately 'top it up' once the powder is in (unless you were to measure the remaining volume in a separate sterile container). The official advice seems much safer.
