Formula milk

Hope this will help : https://www.cdc.gov/nutrition/infantandtoddlernutrition/formula-feeding/infant-formula-preparation-and-storage.html Prepared infant formula can spoil if it is left out at room temperature. Use prepared infant formula within 2 hours of preparation and within one hour from when feeding begins.  If you do not start to use the prepared infant formula within 2 hours, immediately store the bottle in the fridge and use it within 24 hours.
