How often should I bottle-feed my baby?

When it comes to bottle-feeding or breastfeeding, all health professionals recommend ‘responsive’ feeding. This means learning to recognise the early signs that your baby is hungry (often called feeding cues) and never forcing them to finish a feed if they’ve had enough.

"This is particularly important for babies who are formula fed because they can be over-fed and either become sick or put on too much weight (UNICEF UK, 2016; First Steps Nutrition Trust, 2017)."

Responsive feeding can therefore help reduce the risk of obesity (DiSantis et al, 2011; Golen and Ventura, 2015).

Watch our video for tips on how to bottle-feed your baby.

How do I know when my baby is hungry?

Your baby’s early feeding cues can include movements like:

  • sticking their tongue out
  • putting their hands to their mouth
  • starting to get restless
  • opening their mouth and turning their head to the side
  • sucking on their fists or fingers.

(NHS, 2015; UNICEF UK, 2016)

Crying is usually a late sign of hunger. If you wait until your baby starts crying for milk, you might find it more difficult to settle them for a feed (NHS, 2015; UNICEF UK, 2016). If your baby is upset, try to soothe them before you offer a feed. Skin-to-skin contact is great for calming babies.

How do I bottle-feed my baby?

If you’re using formula milk, you’ll need to safely prepare your baby’s feed first. And you can read more about expressing breastmilk for a feed here.

Once you have your bottle ready, find somewhere comfy to sit and feed your baby. Hold your baby close to you. They should be fairly upright, with their head supported, so they can breathe and swallow comfortably. Babies shouldn’t be flat on their backs when they are being fed to avoid the risk of choking (NHS, 2015; UNICEF UK, 2016).

Babies should also never be left alone to feed with a propped-up bottle either, as they could choke on the milk (NHS, 2015; First Steps Nutrition Trust, 2017).

Feeding your baby responsively is a lovely way to bond with them (UNICEF UK, 2016; First Steps Nutrition Trust, 2017). Try talking to them gently and look into their eyes to reassure them during feeds. This helps them to feel safe and loved (NHS, 2015; UNICEF UK, 2016; NHS, 2018).

Focusing on your baby while you’re feeding them also helps to pick up their feeding cues. Research has shown that mums who were distracted by things like using a mobile device or talking to another adult were less sensitive to their baby’s cues. Distraction made mums more likely to overfeed their baby, increasing their risk of obesity (Golen and Ventura, 2015).

Your baby might need short breaks during their feed. Hold them upright and rub or pat their back to bring up any wind (NHS, 2015; UNICEF UK, 2016). Read our tips for bottle-feeding your baby for more information.

Who should bottle feed my baby?

Babies build up trust and confidence during feeding, gradually learning what to expect. This is partly how they develop healthy emotional and social attachment (UNICEF UK, 2016). In the early weeks and months, it might help to keep most of your baby’s bottle-feeds for you and your partner, or one other trusted person (NHS, 2015; UNICEF UK, 2016).

If someone else is bottle-feeding your baby, talk to them about how you feed your baby so there’s some consistency (UNICEF UK, 2016).

How much milk should I give them?

You can usually trust your baby to feed according to their appetite so be guided by them. In the early weeks, your baby might be unpredictable, and their needs may change day by day. Newborn babies generally take quite small amounts of formula to start with in frequent intervals (NHS, 2015).

As a general rule, by the end of the first week most babies will require approximately 150ml to 200ml per kilogram of body weight per day, until they’re six months old. For example, a baby weighing 6kg at the end of four months, would approximately need 900ml to 1200ml of infant formula per day (First Steps Nutrition Trust, 2017).

A formula fed baby will need to be fed according to the guidelines for their weight and age, and the instructions for the brand of formula.

Your baby is likely to need night feeds for first few months of their life. The night feeds will gradually reduce as your baby gets older. Once you introduce solid foods at around six months, they will also need less formula (NHS, 2015).

What if my baby refuses the bottle or is fussy with bottle-feeding?

If your baby is hard to feed after the first 20ml to 30ml then they may need a break at this point. You could try changing their position, putting them over your shoulder to see if they need burping and then offer them the bottle again. If they're not interested, they may just need to feed little and often – this is normal for some babies (NHS, 2015).

If this doesn't help or your baby is often fussy or fights the bottle, ask your health visitor to watch you feed them, as they might have some suggestions (NHS, 2015).

If you’ve breastfed your baby so far, they may be reluctant to take a bottle at first. The different sucking actions needed may confuse them and they may not take a bottle feed from you (Zimmerman and Thompson, 2015).  There are plenty of different things you can try to help your baby.

To begin with, you could ask someone else to offer them a bottle. You can also try a variety of teats. Another tip is to hold your baby in a different position from your usual breastfeeding one. It may help your baby get used to the new way of feeding (Crawley and Westland, 2015; NHS, 2017).

How do I know if my baby is getting enough infant formula?

There are certain signs that will tell you if your baby is getting enough formula needed for them. For example, their weight gain and number of wet and soiled nappies. Generally, your baby should be producing around six wet nappies a few days after birth (NHS, 2017).

Read our article Is my baby feeding well and getting enough milk? to find out more.

What sort of bottles and teats should I use?

You can use whichever bottles and teats you and your baby prefer. There is no evidence that one type of teat or bottle is better than another. Yet the use of larger bottles (more than 6oz) has been associated with increased formula intake among two month old babies, leading to a risk of overfeeding (Wood et al, 2015).

You can buy teats with different sized holes that vary the flow depending on your baby’s age and ability to suck and swallow (UNICEF UK, 2016; Which?, 2018).

Talk to your midwife or health visitor and other parents to weight up the choices and find out more about the options.

It’s important to replace bottles and teats when they look worn. This is because it’s not possible to keep them clean otherwise and worn teats can also disintegrate or split (NHS, 2017).
