In order to qualify for a license, a gym teacher must have a minimum of a bachelor's degree and pass competency examinations covering both general education and topics pertaining to their area of specialty. After a teacher is licensed, they must also meet continuing education requirements set by their state.
Mistake #3: Keeping mixed formula out too long. Formula that is sitting out at room temperature must be thrown away after 1 hour. If it is in the refrigerator, pre-mixed formula (also called ready-to-feed formula) that is opened must be thrown out after 48 hours. Formula that you mixed must be thrown out after 24 hours. Mistake #4: Re-using leftover formula.
It depends what type of formula you are using. Itâs best not to store a feed you've mixed yourself in the fridge to use later. However, you can store ready-made cartons of formula milk, once opened, in the fridge for up to 24 hours. That's because the milk in the carton is sterile. Wash your hands before opening the carton, or use clean scissors. Store the carton in the main part of the fridge where it is coldest.
