How To Choose The Right Portable Bottle Warmer?

Here are a few factors to consider while choosing the right portable bottle warmer that works for you and your baby.

  1. Place of use: If you are someone who prefers lightweight warmer, go for the rechargeable ones that are compact. If you are looking for a warmer to heat the milk on your daily strolls, go for the thermos. The plugin warmers are a good choice if you use them in a hotel room or at home.
  2. Heating/warming: Some warmers can only keep the bottles warm without getting cold. Others can heat the cold and frozen breast milk or water. Choose a warmer that goes with your feeding process.
  3. Compatibility: Check if the warmer is compatible with the bottles that you are using. It is hard for some babies to accept the change of bottles.
  4. Material: Check if the adapters and the leakproof rings of the warmer are made of food-grade material.
  5. Warming time: The time it takes to warm up the bottle is important as some babies might get cranky if there is a delay in feed. Go for the shortest warming time options if this is the case with your baby.
  6. Easy to use and maintain: It should be easy to operate and maintain when moving or at home. Choose a warmer that has minimum parts and is easy to wipe the surface.
