There are a few important guidelines to remember when feeding your baby using bottles, using expressed breast milk or infant formula.

Buying your feeding equipment

You will need a number of bottles and teats, as well as sterilising equipment. There is no evidence that one type of teat or bottle is better than any other. All feeding bottles are made of food-grade plastic, but some have shapes or patterns that make them difficult to clean thoroughly. A simple, easy-to-clean bottle is probably best.

Sterilise and safety check

Make sure your bottles and teats are sterilised. If you’re using infant formula, pay close attention to the instructions on the packet when you make up the feed. Read more about sterilising bottles.

Be prepared

Get everything you need ready before you start feeding. Find a comfortable position to hold your baby while you're feeding. You may need to give your baby time. Some babies take some milk, pause for a nap, then wake up for more. Remember, feeding is a chance to feel close to your baby and get to know them.

Keep the teat full

When feeding, keep the teat full of milk, otherwise your baby will take in air. If the teat becomes flattened while you’re feeding, pull gently on the corner of your baby’s mouth to release the vacuum. If the teat gets blocked, replace it with another sterile teat.

Holding your baby

Hold your baby fairly upright for feeds, with their head supported so that they can breathe and swallow comfortably.

Babies and wind

Your baby may need short breaks during the feed and may need to burp sometimes. When your baby does not want any more feed, hold them upright and gently rub or pat their back to bring up any wind. This may be a very small amount.

Throw away unused formula

Don’t forget to throw away any unused formula or breast milk after the feed.

Go with the flow

Babies differ in how often they want to feed and how much milk they want to take. Feed your baby when they’re hungry, and don’t try to force them to finish a bottle.

Don’t leave your baby

Never leave a baby alone to feed with a propped-up bottle as they may choke on the milk.

Ask for help

If you want support or further information on bottle feeding, talk to your midwife, health visitor or other mothers with experience of bottle feeding.

Common questions about bottle feeding

Why doesn't my baby settle after a feed?

If your baby swallows air while bottle feeding and is then put down to sleep, this may cause discomfort and make them cry. After a feed, hold your baby upright against your shoulder or propped forward on your lap. Gently rub their back so that any trapped air can find its way out easily. But there's no need to overdo it – wind is not as big a problem as many people think.

Why does my baby sometimes vomit after a feed?

Some babies bring up more milk than others during or just after a feed. This is sometimes called ‘possetting’ or ‘regurgitation’ or ‘reflux’. It can be upsetting when this happens, and you may be worried that something is wrong. If it happens often, or your baby is violently sick, appears to be in pain or you’re worried for any other reason, talk to your health visitor or GP.

Check that the hole in your baby’s teat is not too big – giving milk too quickly can cause sickness. Sitting your baby upright on your lap after a feed may help.

If your baby brings up a lot of milk, they may be hungry again quite quickly. Don’t force them to take more milk than they want during a feed. Every baby is different. Some prefer to feed little and often.

Could formula feeding make my baby constipated?

When using infant formula, always use the recommended amount of infant formula powder stated on the packet. Don't add extra infant formula because using too much can make your baby constipated and may cause dehydration.

If your baby is under eight weeks old and hasn’t passed a stool for two-three days, discuss this with your midwife, health visitor or GP, particularly if your baby is gaining weight slowly. Your baby should be gaining weight and have wet and dirty nappies.

Infant formula and allergies

If you think your baby might be allergic to infant formula, talk to your GP. They can prescribe special formula feeds called extensively hydrolysed protein feeds.

Some infant formula is labelled as hypoallergenic, but these are not suitable for babies with a diagnosed cow's milk allergy. Always talk to your GP before using hypoallergenic or soya-based infant formula, as babies who are allergic to cow's milk may also be allergic to soya.
