Quick answer

Breast milk and formula are food under the National Regulations, so the service must handle them safely (r 77) and offer each child food and drink appropriate to their needs (r 78, 79). Under the NHMRC Infant Feeding Guidelines, freshly expressed breast milk keeps 6 to 8 hours at room temperature (26°C or lower) but should be refrigerated, for no more than 72 hours at 5°C or lower at the back of the fridge. Milk thawed in the fridge keeps 24 hours there; never refreeze thawed milk; and once a baby has started a feed, use it for that feed only and discard the rest. Label every bottle with the child’s name and date.

The regulations that apply

DutyRegulation
Staff and volunteers implement adequate health and hygiene practices and safe practices for handling, preparing and storing foodr 77
Children have safe drinking water at all times and are offered food and beverages appropriate to their needs regularly through the dayr 78
Food the service provides is nutritious, adequate, and chosen with regard to each child’s growth and development and cultural, religious or health needsr 79
A child with an allergy or medical condition affecting feeding needs a medical management plan and risk minimisation planr 90

Feeding is also part of the nutrition, food and beverages policy required by regulation 168, and of the food safety rules in food safety requirements.

Procedure for bottles at the service

  1. On arrival, check each container is labelled with the child’s name and the date expressed; refuse or query unlabelled milk.
  2. Store immediately at the back of a fridge running at 5°C or lower, separate from other food, and log the fridge temperature.
  3. Before a feed, two educators check the name on the bottle against the child, so no child receives another child’s milk.
  4. Warm in a container of warm water, not a microwave; test on the wrist.
  5. Discard leftovers from a feed, and send unused milk home or discard it at the times above.
  6. If a child is given the wrong milk, treat it as an incident: notify the parents of both children and record it. See incident reports.

Frequently asked questions

How long can breast milk be kept at childcare?

Freshly expressed breast milk keeps up to 72 hours in a fridge at 5°C or lower (at the back), or 6 to 8 hours at 26°C or lower, under the NHMRC Infant Feeding Guidelines. Milk thawed in the fridge must be used within 24 hours and never refrozen.

Can breast milk be reheated or reused after a feed?

No. Once a baby has started feeding, the milk is only for completing that feed and the rest is discarded.

How should breast milk be labelled for daycare?

With the child's name and the date it was expressed, transported in an insulated container and stored in the fridge as soon as it arrives.

How long can made-up formula sit out?

The NSW Food Authority advises discarding unused infant formula after two hours at room temperature.

What happens if a child is given another child's breast milk?

Treat it as an incident: tell both families, record it and review the checking procedure. Families may wish to seek medical advice.
