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.
I'm just so confused about how long formula can be kept after use and how long those cartons realistically can be open for. Cow & Gate says 24 hours in the fridge, whereas Aptamil says 2 hours in the fridge. Cow & Gate gave LO horrible diarrhoea so I want to stick with Aptamil.
