Formula feeding

Whether you formula feed from birth, alongside breastfeeding, or after a while of breastfeeding, your baby can thrive on formula — and how you feed your baby matters far less than that they’re fed, loved and growing. If formula is part of your feeding, here’s how to do it safely and confidently, without the guilt that too often comes attached.

First, let go of the guilt. Families choose or need formula for countless valid reasons — supply, medical issues, medications, mental health, returning to work, or simply what works for their family. A fed baby and a well parent matter enormously. Commercial infant formula in Australia is strictly regulated to meet babies’ nutritional needs, so you can feed it knowing your baby is getting what they require.

Choosing a formula. Standard cow’s-milk-based infant formula (“stage 1” / suitable from birth) is right for most healthy full-term babies, and the cheapest and the premium tins all must meet the same nutritional standard — you don’t need to pay top dollar. Only switch to specialised formulas (such as for allergy or reflux) on the advice of your GP, child health nurse or paediatrician, not on a hunch or a marketing claim.

Hygiene comes first. Young babies are vulnerable to infection, so cleanliness matters. Wash your hands, and wash bottles, teats and rings thoroughly in hot soapy water (or a dishwasher). For babies under about 12 months, and especially newborns, sterilise feeding equipment as well — by boiling, or using a steam or cold-water steriliser — until they’re old enough to stop, following current advice from your child health nurse.

Making up a bottle safely. Always follow the tin’s instructions exactly, and this order: boil fresh tap water and let it cool (for newborns, guidance is to use water no cooler than 70°C to kill bacteria in the powder, then cool the made-up bottle quickly under a running tap before feeding). Add water to the bottle first, then the correct number of level scoops — never packed or heaped, and never add extra powder or extra water. Getting the ratio right matters for your baby’s health.

Never change the concentration. Adding too much powder can make your baby dehydrated and strain their kidneys; too little means they don’t get enough nutrition. Don’t add cereal, sugar or anything else to a bottle unless a health professional tells you to. Stick to the recipe on the tin, every time.

Feeding your baby. Hold your baby fairly upright and cuddled close, and offer the bottle so the teat is full of milk (to reduce swallowed air). Pace the feed — let your baby pause, and don’t force them to finish; babies know when they’re full, and pushing the last bit can lead to overfeeding and discomfort. Feed responsively, on your baby’s cues, just as you would at the breast.

Never prop a bottle. Always hold your baby and the bottle — never prop the bottle up and leave them, as it’s a choking risk and robs them of the closeness feeding brings. Bottle feeding is a lovely bonding time too, so make eye contact, chat, and enjoy it. Others can share feeds, which can be a real help.

How much and how often. Newborns feed little and often, taking small amounts frequently and building up as they grow; the tin gives a guide, but babies vary, so feed to your baby’s hunger and fullness cues rather than forcing a fixed amount. Wet and dirty nappies and steady growth tell you they’re getting enough.

Handling made-up feeds. Ideally make each bottle fresh and use it straight away. Throw away any formula left at the end of a feed rather than saving it, as bacteria grow quickly in warm milk with saliva in it. If you must prepare ahead, follow safe storage advice (made-up formula kept at the back of the fridge and used within 24 hours), and never re-warm a bottle more than once or keep it warm for long periods.

Combining with breastfeeding. Plenty of families mix feed. If you’re topping up with formula while protecting your breastmilk supply, it’s worth chatting to your child health nurse or a lactation consultant about timing and how to keep supply up — there’s a separate guide on mixed feeding worth a look.

Wind and spit-ups. Bottle-fed babies often swallow a bit of air, so pausing mid-feed to burp them, and keeping them fairly upright for a little while afterwards, can help with wind and comfort. A small amount of spit-up (posseting) after feeds is common and usually nothing to worry about; frequent forceful vomiting, or a distressed baby, is worth raising with your child health nurse or GP.

However your baby is fed, holding them close, responding to their cues and enjoying the connection is what they’ll remember in their body, not the label on the tin. Follow the safety basics — clean equipment, correct mixing, responsive feeding — and lean on your child health nurse for anything you’re unsure about. You’re feeding your baby, and that is exactly what a good parent does.
