There have been a lot of discussions, even among experts, on whether baby milk bottles should be warm or not and the opinions are usually opposite to each other. Some of them say that it is perfectly fine if the baby milk bottle you are giving to your child is at room temperature. The others, however, disagree claiming that it is only natural to provide babies warm milk considering that breast milk is quite warm. Since we understand that this kind of contradictions can be rather confusing, we decided to look into the topic of bottle feeding and try to break the mystery.

Why You Should Warm Your Baby’s Bottle

Newborns and babies up to six months will surely prefer a warm baby milk bottle, and moreover, it is better for them. One reason lies in the fact that breast milk is naturally warm, so babies are simply used to it. The temperature of the mother’s milk is 98 degrees Fahrenheit or around 36/37 degrees Celsius, which is way higher than your average room temperature. So if you for whatever reason need to stop nursing and switch to bottle-feeding, you might find yourself in a situation that your kid rejects the bottle if it’s cold. Babies who are used to breastfeeding prefer their food at body temperature. But when you think about it, no one likes cold meals. Second, during the first months, babies cannot regulate their body temperature well. Warming newborn bottles are essential to prevent issues like upset stomach or feeling cold.
