Parenting is hard work, and a bottle warmer is one way that you can make your life a little easier. While you are changing your child’s diaper, you can warm up a bottle. If you are planning ahead, a warm bottle will be ready when you need it. However, breastfeeding mothers have to search for a warmer that is designed for breastmilk, because it has special considerations. 

Bottle warmers are, typically, designed for formula and breastmilk. There isn’t a warmer only for breastmilk. You can purchase ones designed for traveling or ones that stay on your countertop. Breastfeeding mothers have a few features to consider before you make your final purchase! 

  • Overheating: The largest concern a breastfeeding mother would have about bottle warmers is the heating method. Overheating breastmilk can diminish some of its nutritional value as well as posing a safety risk. No one wants to burn their baby on scorching milk. 

Breastmilk is referred to as liquid gold for some reasons. The number one benefit of breastmilk is the nutritional value offered to your baby. It is full of antibodies, vitamins and essential fatty acids for the development of your child. Our bodies create milk that supports the growth of our child for the first two years of their lives. 

If you don’t want to lose all of the fantastic benefits of breastmilk, you have to make sure you don’t overheat the milk. The nutritional value is degraded when heated too highly. Once the milk reaches a temperature of higher than 104 F (or 40 C), the nutrients start to go down slowly. At 104F, the immunological value starts to deteriorate. 

However, the biggest changes start when the milk reaches 113 F (or 45 C). Degradation starts to take place faster, especially if you leave the milk at this temperature for longer periods of time. So, at what temperature should breastmilk be served? If your baby nurses, your body produces milk at body temperature, around 98.6 F (37 C), and this is the perfect temperature for breast milk.

 You might think this isn’t very hot, and you would be correct! Most breastfed babies are used to lukewarm milk, rather than steaming hot. A child who is breastfed is accustomed to this temperature.

  • The method of Heating: The second most important factor is how the warmer heats up the milk. The most common variety you will find on the market uses water bath technology. It takes longer to heat up the milk, but it does so at a consistent temperature that will not harm the nutritional value of the breastmilk. Water bath warmers circulate water around the bottle, gradually heating up the milk. Breastfeeding mothers benefit the most from these types.

The second method of heating uses steam. Water is put into the warmer, and an internal heating element heats up the water to a higher temperature. The benefit of steam heat bottle warmers is that the bottles are heated much faster. However, the milk reaches a much higher temperature, and the milk can be heated unevenly. If you opt for a steam heating warmer, make sure that you watch the temperature of the milk, so it doesn’t exceed 104 F. 

  • Efficiency: Parents don’t always have time to wait for bottles to warm up. It is important that the warmer works promptly. No one wants to have to wait an hour for the bottle to be warmed unless you are really good at thinking ahead. Mommy’s brain tends to prevent this type of preparation. The best bottle warmer for breastmilk warms a bottle in a timely and evenly manner. Consistency matters; it decreases the risk of hot spots which can burn your child’s mouth.
  • Versatility: Breastfed babies are known for being very selective about the bottle they use. Many parents have to try a variety of choices before finding the perfect choice. There are some warmers on the market that aren’t able to hold a wide mouth bottle, limiting the number of choices you can try. Also, there are certain warmers that only allow you to use plastic bottles. Glass bottles can break if they are rapidly heated. Make sure the warmer you select versatile and can be used with an assortment of bottles.
  • Extra Features: Some bottle warmers come with other features that can benefit you. The more expensive warmers allow you to heat up to baby food jars or containers or to act like a sterilizer. Some warmers sterilize bottles, pacifiers or nipples. Convenient features also include an auto-shut off feature.
