Formula feeding is a valid, loving choice for many families — whether by preference, necessity, or a combination with breastfeeding. Here's everything you need to know to do it safely and confidently.
Choosing a Formula
Most babies do well on standard cow's milk-based formula. Specialised formulas (for reflux, colic, or allergies) should only be used on medical advice. If you're unsure, speak to your health visitor or GP.
Preparing Formula Safely
- Boil fresh tap water and allow to cool for no more than 30 minutes (it should still be at least 70°C to kill bacteria)
- Measure the correct amount of water into a sterilised bottle
- Add the exact number of scoops of powder as directed — never add extra
- Seal and shake well
- Cool under cold running water before feeding
- Test temperature on your wrist — it should feel warm, not hot
How Much Formula Does My Baby Need?
- Newborn: approximately 150–200ml per kg of body weight per day, divided across feeds
- As a rough guide: most newborns take 60–90ml per feed, every 2–3 hours
- Follow your baby's hunger cues — never force them to finish a bottle
Sterilising Equipment
All bottles, teats, and feeding equipment must be sterilised until your baby is 12 months old. Use a steam steriliser, microwave steriliser, or cold water sterilising solution.
Storage
- Made-up formula can be stored in the fridge for up to 24 hours
- Never reuse leftover formula from a feed — bacteria from baby's mouth can contaminate it
- Never freeze formula
