The 5-5-5 rule in breastfeeding refers to a widely recognized guideline that many people previously followed for the safe storage of expressed breast milk. This simple and memorable system provided easy-to-understand timeframes for keeping breast milk at various temperatures, aiming to maintain its quality and safety for the baby.
Understanding the 5-5-5 Rule
For many years, the 5-5-5 rule was a popular method for parents to remember how long their expressed breast milk could be safely stored in different environments. It offered clear, actionable advice across three primary storage conditions: room temperature, refrigerator, and freezer.
Breaking Down Each '5'
Each number in the 5-5-5 rule corresponds to a specific storage duration:
-
5 Hours at Room Temperature:
This aspect of the rule suggested that freshly expressed breast milk could be safely stored at typical room temperatures (approximately 77°F or 25°C) for up to five hours. It's generally advised to use or store the milk sooner if possible to best preserve its nutrients and immunological components. -
5 Days in the Refrigerator:
For short-term storage, the rule indicated that breast milk could be kept in the main compartment of a refrigerator (at or below 40°F or 4°C) for up to five days. Storing milk in the back of the refrigerator, where temperatures are most consistent, is often recommended. -
5 Months in the Freezer:
For extended preservation, the 5-5-5 rule advised freezing breast milk in a standard freezer (at 0°F or -18°C) for up to five months. When freezing, it's helpful to store milk in small, usable portions and label them with the date of expression.
Overview of the 5-5-5 Rule
The table below summarizes the storage recommendations according to the 5-5-5 rule:
| Storage Location | 5-5-5 Rule Duration | Key Considerations |
|---|---|---|
| Room Temperature | 5 hours | Keep milk covered in a clean container. |
| Refrigerator | 5 days | Store in the coldest part of the refrigerator. |
| Freezer | 5 months | Use breast milk bags or freezer-safe containers. |
Evolution of Breast Milk Storage Guidelines
It's important to note that while the 5-5-5 rule was widely followed, recommendations for breast milk storage are periodically updated based on new research and public health advisories. Therefore, always consult current guidelines from reputable health organizations for the most up-to-date information on safe breast milk handling and storage.
