It's important to store diapers at the right temperature to keep them in good condition. Diapers should be stored at a cool, dry place that is out of direct sunlight. The ideal temperature for storing diapers is between 50 and 70 degrees Fahrenheit. If you need to store diapers for a longer period of time, you can keep them in the refrigerator or freezer. However, make sure to let the diapers acclimate to room temperature before using them on your baby.
