Store breastmilk tips

  • On the breastmilk container, write the date. You may identify which breastmilk is the oldest with this.
  • Placing the breastmilk on the refrigerator’s door is a no – this will expose it to a change in temperatures upon opening and closing the refrigerator’s door. 
  • There’s no telling how much your baby can consume in one feeding. Therefore, store small amounts (2 ounces) only in breastmilk containers.
