How to prepare ready-to-feed formula

What is ready-to-feed formula?
Ready-to-feed (RTF) formula is pre-mixed liquid formula that requires no measuring, no mixing and no water. It comes in individual bottles or cartons and is ready to use straight away — making it ideal for travelling, night feeds or situations where preparing powdered formula is not practical.
RTF formula is more expensive per serving than powdered formula, but many parents keep a supply for convenience.
How to use ready-to-feed formula
- Wash your hands before handling the bottle or carton
- Shake the bottle gently before opening
- Open just before use — do not open in advance and leave at room temperature
- Serve at room temperature or slightly warmed — place the sealed bottle in a bowl of warm water for a few minutes. Never use a microwave, as it can create hot spots that may burn your baby’s mouth
- Test the temperature by dropping a small amount on the inside of your wrist before feeding
- Discard any unused formula within 2 hours of opening — do not save a partially used bottle for the next feed
Storing unopened ready-to-feed formula
- Store in a cool, dry place away from direct sunlight
- Do not refrigerate unopened RTF formula unless stated on the packaging
- Always check the expiry date before use
- Once opened, refrigerate any unused portion immediately and use within 24 hours
