Realistically, what is the best way to make up bottles?

I'm expecting in May, and i've just read the WHO's guidelines on how to make up a bottle... well bloody hell, i won't be doing anything else if i do it that way! I mean, what are you supposed to do when you're out and about, or at night?

DS1 was born 6 years ago and back then, i would put the bottles in the dishwasher overnight, boil the kettle when i came down in the morning, leave it to cool for a while, then fill all of the bottles with water, seal them and store them in the fridge for when i needed them. All i had to do was add the formula.
Clearly i was doing it wrong! But really, is there any real reason why it can't be done this way? Or is there a better way? Or should i just stop being so lazy and do it how the WHO recommends?

Yes there is a good reason. Formula powder can contain bugs that need to be in contact with water that is 70 deg or hotter to be killed off. Powder is not sterile and the bugs can be v serious.

Sevond best way is make up as directed and then flash cool and refrigerate.

We made up feeds in a morning with boiled water then flash cooled and stored in the fridge, warming in a jug of hot water as necessary.

For out and about I would use a carton.

If we have another baby I will consider getting one of these and making up fresh each time Hot water dispenser

Well that doesn't make sense, narmada if i left boiled water in the kettle for 30 mins, as per the instructions, it wouldn't be over 70 degrees. Our kettle has a thermometer on it, it's about 50 degrees after 30 mins. So it wouldn't kill the bacteria anyway!

It does make sense smile. Boiling the water kills the bacteria. You cool it then make the feed and refrigerate it before the bacteria has a chance to breed

Fairylea Fri 11-Jan-13 19:29:47

You're not boiling the water to kill the bacteria in the water. You need it hot enough to kill the bacteria in the powder.

It's a guideline - 1l of water in a well insulated container will cool at 1C per minute (based in the specific heat capacity).

However that assumed your water is at 100C when boiled, that your kettle has good insulation as that you boiled a litre...

As you have a thermometer on the kettle use it to see when it's at 70.

It's vital to add powder to hot water. What you do after - use straight away or flash cool and fridge to reheat - makes little difference as long as the bottles remain sterile until in baby's mouth and are discarded after 2 hours at room temp.

I use just boiled water, flash cool and then store in the middle of a very cold fridge. I only make 2 or 3 at a time so they aren't sitting around very long. I use sma ready made bottles and the screw on teats when I go out.

hazeyjane Fri 11-Jan-13 19:35:14

The guidelines have been in place since at least 2006, when I had dd1.

I used a mixture of cartons, and making up formula, using >70 degree water, then topping up with cooled boiled water.

12ylnon Fri 11-Jan-13 19:36:33

So i can still use it even though the water is only 50 degrees after 30 mins?

Fairylea Fri 11-Jan-13 19:39:35

No, I'd use it after its literally just been boiled. Then you can't go wrong. Or leave it for just ten mins or so. It needs to be super hot.

Pooka Fri 11-Jan-13 19:40:53

No - the water you mix with the powder has to be 70 degrees or slightly over. S not immediately boiled, but not after 30 mins if your kettle doesn't keep it to 70 for that period.

The temp is necessary kill the bacteria that might be in the powder.

When DD was on 6 bottles a day we used to make 3 up in the morning and 3 in the evening, so they were not in the fridge longer than 12hrs. We use the water about 20 mins after the kettle boils to make up the feeds then flash cool in a sink of cold water. Another method... If making a 8oz bottle mix 8 scoops powder with 2oz of boiled water (over 70c) then add 6 oz cooled boiled water. That way the hot boiled water kills the nasties in the powder and the cooled boiled water gets the bottle to room temp straight away.

Ok so- boil the kettle, fill the bottle, add formula, cool it on the counter top/ in iced water. Use it.
Whats stopping me from making up two at once and keeping one in the fridge to reheat when i need it?
Sorry i'm being so dense, but every website i look at says something different.

Fairylea Fri 11-Jan-13 20:07:49

Cool in iced water or in a sink full of cold water - don't leave it on the counter to cool as it won't cool quickly enough and the bacteria will multiply.

You can make up a few in one go. I think most people just make 2 or 3 so they are reasonably fresh.

You won't find any info about doing it that way online as officially it's still compromise - the proper guidelines say make each one fresh. But I think most people find that impossible or very stressful so make a compromise.

I saw the WHO advice about the 70 deg for the first time in a travel question on here recently.
I wasn't aware of it before, so the advice wasn't about / prevalent at the time I had my children.

So I googled it to find out what it was about. Most of the articles that came up were actually about not heeding that advice! Apparently there is greater risk of scalding yourself dealing with water that hot, than risk from the bacteria. The risk was .001 % of infection by the bacteria, and that careful storage and preparation of the formula was more important in it's prevention.
Whereas water over 70 deg can scald / cause sever burns to a baby within a second or two on the other hand, so the argument was that risk of that is greater, using water that hot.

Obviously it's important to sterlise / prepare the way that you feel most comfortable with, I'm not trying to convince those that are happy to do so to stop boiling the water to that temperature. smile.

But I thought that might help reassure you OP, since you didn't follow those guidelines with your first, to be able to weigh up the risks for yourself, and see if you thought it was worthwhile to do so, in answer to what is 'best'. smile

Sorry Ginger, but those guidelines have been in place for at least 6 years.

I just googled 'making up formula' and the first page was the nhs one which recommends exactly as per WHO's guidelines.

claricestar Fri 11-Jan-13 20:15:58

my tip for flash cooling: keep a load of those plastic ice cubes in the freezer to put in your sink/bowl of cold water. my bottles cool a lot faster that way and a lot less faff than making ice cubes.

hazeyjane Fri 11-Jan-13 20:20:16

Also, the 'bacteria' that led to the guidelines being as they are is a very particular nasty called e.sakazakii, and whilst the risks are small, the contaminant has been found in powdered baby milk and is fatal.

12ylnon Fri 11-Jan-13 20:21:05

gaskell thats very interesting, i guess i'll just have to see. Tbh, theres probably more of a chance of the baby picking something up from shoving a toy or it's own fingers in it's mouth than from infant formula.
I'm sure the guidelines were different then! Everyone i knew did it the same way as me blush i swear i'm not a slob!
Thanks everyone!

12nylon, lots of people don't know how to make formula up correctly.

The bacteria that can be found in powdered formula milks are much worse than anything a baby will find othe floor and put in their mouth. Would you give our baby raw chicken to eat? No, we'll formula powder can carry salmonella as well as e.sakazikii, which babies in Europe have died from due to incorrectly made up formula.

The risk may be small, but the consequences are potentially huge.

gingergaskell Fri 11-Jan-13 20:37:29

Probably Hazey, but like OP, with my children born in 2006 and 2008, no one else I knew at the time did so, so it was not the norm, or common knowledge. This was across 2 x countries, one of my children was born in HK and one here in the UK {the youngest}.

And again to reiterate, I'm not trying to challenge or advise against it, just stating the risk. smile.

narmada Fri 11-Jan-13 20:45:33

But the point is that e.sakazakii - or cronobacter- Is very dangerous - think sepsis or bacterial meningitis and a historical mortality rate of 40 to 80%. The risks are greatest in tiny newborns. Why take unnecessary risks?

narmada Fri 11-Jan-13 20:48:31

Oops cross post. But I don't see the point in 'we didn't do it in my day and we were all fine!' type arguments.

12ylnon Fri 11-Jan-13 20:54:30

I just read an article on the government food safety website in NZ that states that cronobacter could also be found in ready made formula and breast milk, so really, nothing is safe. In fact, this website says that the lowest instances of cronobacter contamination was in ready made formula, even lower than bm.
