Getting the temperature right
It won’t hurt your baby to have cold infant formula, but many babies prefer formula warmed to room temperature. If your baby doesn’t mind cold formula, feel free to serve it cold.
Standing the bottle in warm to hot water is the safest way of warming the milk.
Bottle warmers are convenient and safe as long as they have a thermostat control. Leaving the bottle in the warmer for more than 10 minutes might cause bacteria to breed in the formula. These bacteria are a common cause of diarrhoea.
Microwaves aren’t the safest way to warm milk, because they don’t warm milk evenly, and ‘hot spots’ in the formula might burn your baby’s mouth. Closed bottles can also explode in the microwave.
Check the temperature of the feed by shaking a little milk from the teat onto the inside of your wrist. It should be about room temperature.
Giving baby the bottle
Make yourself comfortable and cuddle your baby close to you, holding him gently but firmly. It’s better for him to be on a slight incline so any air bubbles rise to the top, making burping easier.
Put the teat against baby’s lips. She’ll open her mouth and start to suck. Keep the neck of the bottle at an angle so it’s filled with the milk mixture.
When your baby stops sucking strongly or when he has drunk about half the milk, gently remove the bottle and see whether he wants to burp. Once you have tried burping your baby, you can offer the bottle again.
When baby doesn’t finish the bottle
If your baby goes to sleep unwrap her, put her over your shoulder, rub her back and stroke her head, legs and tummy to wake her up. A nappy change is a good way to wake her up if that doesn’t work.
Wait until your baby is properly awake before offering him the rest of the milk.
If your baby doesn’t want to finish the bottle don’t encourage her to, because she might have already had enough. Let her decide how much she wants.

To test the flow of the infant formula, hold the bottle upside down when it’s filled with the formula at room temperature. The formula should drip steadily but not pour out.
If you have to shake it vigorously to see the drip, the flow is too slow. Your baby might go to sleep before she drinks what she needs.
A little leakage at the corners of baby’s mouth while he feeds is nothing to worry about – as he gets older this will stop.
If you have trouble finding the perfect teat, go for a faster teat rather than a slow one.
There’s no set amount of food or number of feeds your baby should have. Different babies drink different amounts of infant formula. Some might have some feeds close together and others further apart.
The following is a general guide:
- Babies need around 150-200 ml per kilogram of body weight per day until three months old, then 120 ml per kilogram of body weight.
- Babies commonly have 6-7 feeds every 24 hours, but this will vary depending on their needs and the length of feeds – feed your baby whenever she’s hungry.
You can also use the chart on the formula tin to see how much infant formula to give, but information about quantity for age on formula tins is also just a guide. It might not necessarily suit your baby.
Some babies never drink the ‘required amount’ for their age and size, and others need more. Plenty of wet nappies, consistent weight gains that are not excessive and a thriving, active baby mean all is well.
Babies who fall asleep while bottle-feeding can draw liquid into their lungs. They might then choke on it or inhale it. This is like what happens when you have something ‘go down the wrong way’.
It’s more dangerous for your baby than it is for you, though, because your baby isn’t as good at waking up if something interferes with breathing.
Although it’s more likely that your baby will cough and be uncomfortable, you might want to avoid the risk altogether.
If babies get used to having a bottle-feed every time they fall asleep, they might develop an association between the bottle and sleep. They might then find it hard to fall asleep without a bottle.
Risk of tooth decay
Milk is quite high in sugar. Soaking your baby’s teeth in it overnight can cause tooth decay. Read more about tooth decay.
Risk of ear infections
When a baby drinks lying down, milk can flow through to the ear cavity, which can cause ear infections. Read more about ear infections.
Holding your baby during bottle-feeding can help you bond and connect. It’s better for your relationship than propping your baby up in bed with a bottle. It’s also a great opportunity for you and your partner to take turns bonding with your baby.
Using a feeding cup
When your baby is around six months old, you can start using a feeding cup to teach your baby how to sip drinks from a cup. You should continue to thoroughly wash the feeding cups containing infant formula or breastmilk until your baby is 12 months old.
