It has never happened to me because my three children have taken a minimum breast up to two years and, except for the medium, who took a bottle a few days in the hospital, prematurely, the others have not tried it and I have never prepared any bottle. But I do have a friend with whom I spoke a few days ago that he is half zombie because that waking up at night to prepare bottles has exhausted him (and that he only prepares them, that she gives them to him ... if we sometimes give penica)
Before his comment, I decided to tell him a trick that nobody had told him before: "Boy, if it is such a problem to prepare them, leave them done before you go to sleep." He made me look surprised, he asked "Can that be done?" and I answered yes, and how to do it. So if you are tired of preparing the bottles at night, or if you wake up so asleep that there is a risk that you are wrong with the preparation, do not miss this entry in which I explain how to leave them ready before going to bed.
The powder is not sterile
Take this opportunity to comment once again, because it comes to mind. The dust that comes in cans of artificial milk is not sterile and, consequently, may contain certain microorganisms such as Cronobacter sakazakii or Salmonella, capable of producing mild to severe infections, especially in newborn or premature babies. He Cronobacter sakazakiiFor example, it can cause infections as serious as meningitis or bacteremia (presence of bacteria in the blood), as you can see in this study.
You will think that "well, it sure only happens in a specific lot", but it seems that it is not, because some researchers went to 5 artificial milk factories to see how far the Cronobacter sakazakii It could be found in them and of the 298 environmental samples they took in them, 32% contained the pathogen. How much of that ends up in powdered milk, it is not known, but that 1 in 3 samples is positive is not very hopeful.
By this I mean, once again, that the water we use to prepare the bottles has to be boiled, not by water, but by the dust, because at 70ºC the risk is minimized, because at that temperature the water begins to eliminate these microorganisms. Well, to be honest, it takes just over 20 minutes at more than 70 ° C for the decrease in Salmonella and of Cronobacter Sakazakii It is remarkable, but if you prepare them as I will tell you then surely the final milk is better than if they were prepared with the water at room temperature, without heating, as many people do.
How to prepare the bottles
Before going to bed, knowing that the baby is going to wake up two or three times, prepare two or three bottles. Well, you can actually prepare more because the bottle can remain prepared in the fridge 24 hours. But you decide to do three for the night and tomorrow, if that, you will be preparing more on the fly (the proliferation of other bacteria will always be somewhat less).
Let's say your baby is drinking 90 ml of milk per bottle. As you are going to make 3 bottles, you put 270 ml of bottled water (a priori is better than the tap) in a clean saucepan and put it to heat until it boils. Once is boiling you know it's 100 ° C. As at this high temperature it is possible that the dust, on contact, agglutinates and hardens, making a lumpy mixture, and how at this temperature could activate bacterial spores, the ideal is to mix the water with the powder at a temperature of between 70 and 90ºC. After boiling, just wait 5 minutes for the water to reach 90 ° C and then pass it from the saucepan to the bottles.
In case you spend more time, calm down, you are still in that temperature window, unless 30 minutes have passed. The water is then considered to be below 70 ° C and is no longer useful. That is, after boiling, we wait for 5 to 30 minutes (better to be closer to 5 than 30) and put the water in the bottles. Then we throw the appropriate powder pots to each bottle. In the case of the example, as were 90 ml bottles, 3 flat pots, one for every 30 ml (or as indicated by the canister, eye).
Shake the bottles for the mixture to take place and put them in the fridge, which should be below 5ºC. We have said that it takes a few minutes for the two microorganisms to be eliminated. For those minutes happen now, in the time we have prepared them, we have mixed them and put them in the fridge. Inside the fridge the cooling is faster, of course, but if we have prepared the bottles at 90 ° C the time to eliminate pathogens is also much less (one 5-6 minutes) and it will still take a few minutes, in the fridge, to drop below 70ºC.
When the child wants to eat
We have put them in the fridge and we have gone to sleep. The time comes when the baby wants to eat. Then we take one of the bottles and give it to him. Cold? Well, if you like cold, go ahead, you can take it cold (at least that's what the American Academy of Pediatrics says), but it is usually more pleasant to take it mild, I think.
You take a bottle and heat it, or under the tap, with hot water running, O well Bain-marie. The microwave is not a good idea because it does not always heat evenly and we could burn the child's mouth. Once hot, we put a few drops on the inside of the forearm and when we notice that the milk is warm (it does not need to be hot) we give it to it.
With this system we will have saved a few minutes (with the theme of boiling the water and waiting for five minutes, which we did before bed and so we do not have to do it now) and we will know that you are taking a well-prepared bottle.
If this system does not convince you, you can always skip the recommendations, prepare it with the bottle water at room temperature, which is much faster, shake the powder and go. You finish before, even if you give a badly prepared bottle with which your child has more risk of ingesting the microorganisms mentioned.
