It is a common misconception that warming breast milk or formula slowly is safer. There are 2 reasons why this messaging has been miscommunicated or misunderstood.
First, some bottle warmers lack the capability to warm quickly and safely. The brands that sell these bottle warmers spin the marketing messages to make you believe that slower is safer when what they are really saying is, we just can’t do it.
Second, there are unsafe ways to quickly warm breast milk and formula. For example, you should never warm breast milk and formula in a microwave. Doing this can create hotspots that are dangerous for a baby and can also damage the nutrients in breast milk.
The good news is that the BisbeeBaby Keddle can safely warm breast milk 2x faster than any other portable bottle warmer on the market. Before I explain how the Keddle is superior, let’s recap on why current bottle warmers don’t cut it.
Bottle warming methods
The most common way of warming breast milk and formula is to use a bottle warmer. Most traditional bottle warmers use steam. The problem with steam is that the bottle can get very hot (>200°F) which may damage breast milk nutrients and can burn your hand when you pull the bottle out of the bottle warmer.
Most bottle warmers also don’t measure liquid temperature. There are a few bottle warmers that have added liquid temperature sensors. Unfortunately, these warmers can take up to 15 minutes to warm a typical bottle.
How does the Keddle warm quickly, evenly and accurately
The BisbeeBaby Keddle can warm breast milk and formula quickly (<4 minutes) and accurately (within 2°F) because it is the only portable breast milk and formula warmer that uses multiple heaters and liquid temperature sensors. The Keddle uses proprietary technology to determine which heating cycle is most appropriate for the volume of liquid being warmed.
The Keddle starts a warming cycle by determining how much liquid has been added. Using this information, the Keddle can adjust how the heaters warm the liquid. For example, if you add 2oz of liquid, the Keddle will limit the amount of power sent to each heater so that it doesn’t overheat the liquid. If you warm 8oz of liquid, the Keddle will maximize the amount of power to each heater to warm as quickly as possible. This ensures that all volumes of liquid are warmed quickly, evenly and accurately.
The vessel within the Keddle does get a few degrees hotter than the actual liquid temperature. If it didn’t, warming breast milk and formula could take hours. The good news is that a few degrees is significantly better than what you’d see in a typical steam bottle warmer. For any liquid, excluding breast milk, the higher vessel temperature isn’t a concern. Keep in mind, the liquid temperature is still even and accurate. For breast milk, we recommend that parents limit the maximum warming temperature to 98°F. This ensures that the breast milk never touches unsafe temperatures that could damage breast milk nutrients.
