How to Heat up Baby Bottles

Aw…does baby want their bottle? Well actually yes, they do. In fact, they want it frequently and can be particular about the temperature the good stuff is heated to.

Beyond the bottle (standard for this post), some babies prefer their milk warmer than others. If your little bundle of joy falls into this category, this post will be of extreme use to you.

The following is a Step by Step Guide to safely and effectively heating your baby’s bottles using simple methods within your home.

    What You Need

    In order to carry out the following steps, you will need the following:

    - a baby (congratulations by the way)

    - a safe, secure and clean baby bottle (for a Step by Step Guide on Sterilizing Your Baby Bottles, click here)

    - the desired amount of milk or formula

    - your kitchen sink

    - a large clean pot

    The last item (the pot) is for those who elect to use the stove top to heat their bottles. This and another method are outlined below. Both are simple and depend on your preferences as well as those of your baby.

    Fill Your Bottle with Milk

    Begin by filling the clean baby bottle with the desired amount of milk or formula.

    Run the Tap

    Begin by running your tap. Make sure you have turned the tap to the warm/hot setting (depends on your manufacturer and model).

    If your baby’s milk does not have to be very warm, it is suggested that angle the bottle slightly and place it underneath the running hot water. Be sure that the nipple and ring at the top of the bottle are not submerged or taking it water as this will dilute the good stuff in the bottle. The purpose of this is to heat the bottle with running water. If you elect to do this, proceed to Step 6.

    If your baby prefers warmer milk, you will need to put your pot and stove to use. Using the running tap, fill the pot with water and place it on the active stove top.

    In Hot Water

    Heat the water for a few minutes. Do not let the water boil. Boiling water would be too hot for heating the bottles and would cause a delay in that you would have to wait for the water to cool slightly.

    Put the Bottle in

    Turn off the stove and place the bottle’s base in the water. The more of the bottle that is covered, the faster the warming process will be. Note again to not submerge the nipple and ring of the bottle underwater as this will dilute the milk in the bottle.

    Know Your Baby

    Keep the bottle in the water for what you deem to be the right amount of time. This is based off of what your baby’s desired milk temperature is. If they prefer their milk warmer, you will have to keep the bottle in the pot for longer than you would to feed a baby who prefers slightly above room temperature milk.

    Test the Temperature

    The easiest and most effective way to test the temperature of the milk is in the inside of your wrist as the thin skin of the area makes it sensitive to heat. Turn the bottle and shake a few drops onto this area to determine if it is too hot for your baby. The milk should feel tepid and not hot. If the milk seems hot, let it cool by standing for a couple of minutes. Test again as required.

    Note: Always test the temperature of the milk to determine that it is not hot.

    Dry the Bottle

    Use a clean cloth or paper towel to remove the water on the outside of the bottle from the heating process.

    Feed Your Champion

    Just before feeding your baby, shake the bottle thoroughly to distribute the warmed milk evenly. You are now ready to feed your child.
