Does boiling water kill nutrients in the formula milk?

[Ano]

Hello,

I've made another mistake, apparently. I'm supplementing my mother milk with formula milk (despite pumping every three hours, I can only get 90 ml per day so far).

Anyway, I was stupid enough to use boiling water to make the formula milk (Aptamil Pronutra), and then I let it sit in a cold water for a few minutes to let it cool. This is despite my parents already reminded me before to let the boiled water cool down a bit before putting the milk powder in it as not to kill the vitamins in the powder. I forgot about it and did everything automatically (and wrongly!).

So I suppose I have killed all the good nutrients in the formula milk and my baby doesn't get enough vitamins in the first two weeks of his life? This makes me feeling awful.

My infant is today 15 days old. The visiting midwife said just now that it's okay, since he gains weight regularly, and I just need to make the formula milk differently from now on. He now weighs 3900 grams (300 grams more than last week), but maybe she said this just so that I did not go completely bonkers? I got a feeling that I'm the only mother who made this stupid mistake, because it's clearly written on the package too (silly me!). (My husband also missed that, because we live in Germany, and he does not read German).

Is it possible that infants gain weight but they actually do not get enough vitamins? Will this affect his brain and his antibodies or other things I don't know?

Thank you in advance!

I always did it that way when I needed to and I have a thriving 7 and 9 year old.

Mind you, I also did the boil the water, pour into sterile bottle and then add the powder when needed and reheated the water but that’s not the right way anymore either

I'm sitting next to my huge 21yeqr old who was formula fed and seems to have done ok on it 😉

Rest assured, your baby won't suffer from two weeks of deficient formula.

I give my breastfed baby vitamin drops, not strictly necessary for formula fed babies but if you are worried perhaps you could get some drops?

I believe the reason they say to leave it to cook is to reduce the risk of the person making the bottle burning themselves. It doesn't destroy the nutrients. You dont need to worry.

It'll be fine.

I did not know this! So it's got to be more than 70°C to destroy bacteria but less than 100°C to not kill the nutrients!?

I often make it with boiling water, I was told that the 70°/wait thirty minutes guideline was to reduce the risk of scalding.

Same here

I thought you were supposed to let the boiling water cool for a bit so that you don't get scalded when you're trying and shake it to mix the formula 😕

What I thought too!

Midwife here. Formula is heat treated during manufacture at temperatures higher than boiling point. The nutrients survive this process so they will be fine with boiling water. General advice is now to boil the kettle, leave for 20 mins or so and then add the formula. The water needs to be above 70 degrees when you add the formula to kill any bacteria that may have grown in the formula. You won't have done any harm to your baby 😊

Thank you for your messages. If it's only because of the scalding risk, then I suppose it might be okay (?). Indeed I haven't read any official source about hot water killing the nutrients. To be sure, though, I now let the boiled water cool down a bit (down to 70°C) before mixing it with the formula.
