Bottle Feeding

• Bottle feeding on demand means responding to your baby’s hunger cues rather than sticking to a fixed feeding schedule. You feed your baby when they show signs of being hungry, not by the clock. 
• Feeds can be less predictable and more frequent, especially in the early weeks and it may take time to learn your baby’s hunger cues. 
• Some families prefer full flexibility, while others mix on-demand feeding with a loose routine. 

Feeding your baby is one of the most instinctive things you’ll do as a parent - but it also comes with a lot of decisions.

With bottle-feeding, one approach often discussed is feeding on demand (also called responsive feeding) rather than following a strict schedule.  

Feeding when your baby shows signs of hunger seems entirely natural. But how does that work in practice when you’re using a bottle? 

Our helpful guide helps you explore how to bottle-feed on demand, what works and what to watch out for, so you and your baby can find a rhythm that feels right. 

What does on-demand bottle-feeding mean?

On-demand feeding means you offer a feed when your baby gives you hunger cues. Rather than strictly every so many hours or exactly according to the clock.

The NHS describes responsive feeding as “feed your baby when they show they’re hungry, rather than following a rigid schedule.”

With bottles, this may mean keeping one ready, reducing pressure to finish it, and trusting your baby’s signals of hunger and fullness. 

Is feeding a baby on demand bad?

No, feeding on demand is not necessarily a bad thing, particularly early on in your baby's life. In fact, many experts recommend feeding your newborn baby on demand, as each feed helps to support healthy growth and development. 

If your newborn is always hungry and wants to feed constantly, let them. Newborns should ideally eat a minimum of eight times a day anyway. 

Should I be feeding my baby on demand or on a schedule?

Choosing whether to feed your baby on demand or feed them according to a schedule really depends on your baby's age and appetite, after all, every baby is different. 

Feeding patterns tend to emerge at around 3-4 months of age, making it easier to feed your baby according to a schedule if it suits 

The pros of bottle-feeding on demand 

When you respond to your baby’s cues rather than the clock, you often support their natural appetite, which can help the baby feel more comfortable and reduce chances of fussiness or crying from hunger.

The NHS highlights that responsive feeding can also lower the risk of over-feeding. 

For bottle-feeding families, this approach may offer a more flexible day-to-day rhythm - especially helpful if you're balancing work and travel regularly. 

The cons of bottle-feeding on demand 

While feeding responsively has many advantages, it can bring challenges. Without some routine, it might be harder to plan sleep, days out or simply anticipate when the next feed will happen. This unpredictability can feel tiring for parents. According to feeding professionals, demand feeding can make day-to-day organisation more difficult.

Another concern with bottle-feeding on demand is the potential for overfeeding. Unlike breastfeeding where the baby controls the milk flow, a fast-flow bottle or encouragement to finish the bottle may lead to the baby taking more than they need. Encouraging your baby to finish the bottle may override cues of fullness in some instances

What if my baby is still hungry after a feed?

Newborn babies often want to feed around the clock, so if your newborn still seems hungry after having been fed, don't be alarmed, this is completely normal behavior. 

It's important to remember that your baby's appetite grows as they do, so if your baby still seems hungry after a feed, then they might be going through a growth spurt. 

Growth spurts typically occur at around: 

• 7-14 days old 
• 3-6 weeks old 
• 4 months old 
• 6 months old 

If you're concerned that your baby isn't eating enough, we recommend seeking advice from a healthcare professional. 

Bottle-feeding on demand vs. scheduled feedings  

When it comes to feeding your baby, there’s no ‘right’ way, just what works best for your baby and family.

With on-demand bottle-feeding, you respond to your baby’s hunger cues and feed them when they show signs of wanting milk, such as rooting, sucking on their hands, or becoming restless. This approach supports your baby’s natural appetite and helps them learn to regulate how much milk they need. 

Comparatively, scheduled feeding follows set times or intervals between feeds, i.e. every three or four hours. Some parents prefer this structure because it can make planning naps, outings, and sleep routines easier.

However, sticking too rigidly to a schedule can sometimes mean delaying a feed when your baby is genuinely hungry, or offering milk when they’re not. 

Parents might find a balanced approach works best, loosely following a routine but still watching for their baby’s cues. Over time, babies naturally settle into more predictable feeding patterns, whether you start with an on-demand or scheduled approach. 

Can you feed on demand with formula? 

Again, it's generally recommended to feed your baby whenever they seem hungry - and this advice includes babies who are formula fed. 

Newborns who are formula fed are likely to want to eat approximately every two to three hours. As your baby grows and their stomach can hold more milk, you may find that they want to eat more like every three to four hours.
