I often read the recommendation that milk for newborns and infants (breast milk or infant formula milk) should have body temperature (~ 37°C). Usually, this recommendation is just stated as a fact (without scientific reasoning) or with some useless "generic" reasoning ("It's best for your baby", etc.).
Hence, my question: Will bad things happen if milk is fed at room temperature (20-25°C) instead? If yes, which bad things? If not, why is body temperature recommended?
Note: I do know that milk (breast milk or infant formula) should not be "old", due to bacterial growth. That is not the question. I am asking about "freshly prepared" milk.
