No microwaves please, we're babies

There is no health reason to feed a baby warmed milk it is a matter of what your baby prefers or gets used to. When you're ready to feed your baby, you can warm a bottle in a pan of hot but not boiling water, or by running it under the tap, you can also buy a bottle warmer designed for this purpose, it is not a good idea to warm bottles in the microwave as it can destroy the nutrients and it is suggested that there could be pockets of heat. Try to get your baby accustomed to drinking bottles at room temperature or cold you save yourself the time and hassle of preheating bottles, especially when they are crying to be fed, or your somewhere where you can't warm the milk.
