PediaSure Complete can be heated so that it is warm, but should not be made so hot as to burn the mouth. Be sure to check the temperature of the product before offering it to your child. (Although it is not necessary to check the temperature with a thermometer, if one is used, the temperature should be in the range of 37°F to 43°F.) If you use a microwave to warm the product, you must pour it into a microwave-safe container prior to heating and ensure it is evenly heated and at an optimal temperature or else serious burns can result.
