At 4 months of age, babies are settling into a feeding routine and becoming more efficient at the breast or bottle, drinking about the same amount over the course of the day as they have been consuming up until now. The difference: babies can often be gently guided toward drinking more during the daytime, which can lead to longer stretches of uninterrupted sleep at night.

What to Expect at 4 Months

At this age, many babies are typically settled into a daily feeding routine and can communicate to their caregivers that they are hungry or full through their actions. If your schedule still feels random, it’s okay: keep feeding on-demand and offer the breast or bottle when baby shows signs they are hungry. This gradually builds a predictable schedule of feeding times. 

➔ Baby eats breast milk, formula, or a combination. 

➔ Baby typically eats 22 to 34 fl oz (650 to 950 mL) per day. 

➔ This is a common time for a growth spurt and increased intake. 

➔ Baby feeds every 3 hours, but it varies. Watch for hunger, not the clock. 

➔ Baby may get distracted, then want to feed again shortly after stopping.

➔ Baby typically feeds overnight at least once (and often more). 

➔ Cluster feeding (every 30 to 45 minutes) may happen before bed. 

➔ Baby may eat more at each feed with longer stretches between feeds. 

➔ Baby stays awake for 1.5 to 2 hours, and naps 3 to 4 times per day. 

➔ Sleep disruptions (at naptime and overnight) are common.

Some families offer pureed foods around this age, however, leading medical institutions recommend exclusive breastfeeding and/or formula feeding until 6 months of age, and waiting to start solids until baby shows all of the signs that they are developmentally ready.

If baby is exclusively breastfed

This is a great age to introduce a bottle if you would like them to be part of your feeding routine. Introducing bottles can get more challenging as baby gets older. 

If baby was born prematurely

They may still be getting the hang of feeding. Your medical and therapy teams can provide individualized support. 

★ Remember

You cannot force a baby to take in more than they want, or push them to eat more often or larger amounts than they want. Continue feeding on-demand and following baby’s lead, which gradually leads to a predictable feeding schedule.

Sample Feeding Routine

Use this schedule as a starting point and adapt in a way that works for you and baby. It is okay if your baby’s routine differs. You can trust that your plan is working as long as baby is regularly peeing and pooping, and baby is growing with themselves as their own benchmark. As always, discuss your plan with your medical provider as questions come up.

How much should baby eat at 4 months of age?

A 4-month-old baby typically consumes 22 to 34 fl oz (650 to 950 mL) of breast milk or formula over 24 hours, and daily feeding routines vary from baby to baby. 

All of these scenarios are normal. It is also normal for consumption to vary from one day to the next, especially when they are ill or tired. 

Talk to your doctor if baby regularly wants to feed every 30 to 60 minutes during the day or night and they are not starting to sleep for longer stretches. While it is normal for babies to cluster feed in the evening (feeding every half hour or so before bedtime), they may benefit from lactation or medical support if they regularly want to feed every 30 to 60 minutes.

Signs Baby is Eating Enough

✔ Content and alert

They're regularly alert and playful.

✔ Producing wet diapers

They make several wet diapers daily.

✔ Energetic

They are ready to explore most days.

✔ Growing steadily

They are growing along their curve.

There is no “right” answer to how much a baby needs to grow and thrive. As long as they are growing and following their unique curve, trust that baby is eating to meet their nutritional needs. Speak with your medical provider if you are concerned about baby’s intake or weight gain. 

Keep in mind that nursing and bottle feeding offer more than nutrition; some babies remain latched for long periods of time for soothing. This is normal, and it is usually nothing to worry about as long as baby is happy and steadily growing.

Baby Feeding Tips 4 Months

Build a routine.

Babies tend to settle into a predictable routine when they are fed on-demand. When baby shows signs of wanting breast milk or formula, offer it. When they show signs they are done, stop the meal. It’s also completely OK if you do not focus on routine (if this works for you)!

Take burp breaks.

About halfway through feeding, pause and let them burp. This way, baby can get out any swallowed air, which decreases the chance baby will be uncomfortable and gassy.

Pace bottle feeding.

Let baby feed for 5 minutes or so, and then gently remove the bottle and let them suck on your finger or a pacifier, then return to the bottle. This mimics the flow of breastfeeding, aids in digestion, and allows baby to better listen to their belly. 

Feed more during the day.

Try to breast or bottle feed more frequently through the day. For some babies this helps get longer stretches between meals at night (and more consistent sleep)!

Feed to sleep?

Feeding to sleep is a very common practice, as babies naturally get drowsy when feeding. It’s also common for families to want to dissociate feeding and sleep. This is a personal decision, and there isn’t strong evidence to suggest that one method is better than the other. Do what works best for you. 

Practice with bottles. 

This is a good age tointroduce a bottle to exclusively breastfed babies if your goal is to help them learn to bottlefeed, even if only intermittently. Start with offering a bottle once a day. At this age, they are using their oral reflexes to suck and swallow, and these reflexes begin to integrate around 4 months of age. Babies are often more open to taking a bottle before these reflexes integrate.

Should my 4-month-old baby be eating solid food?

Generally, no. At a baby’s 4-month well-child visit, your pediatrician may bring up solid food—and they may even suggest that you start introducing purees. While there is not enough research to back up the idea that there are developmental advantages to starting solids before baby is ready, there are benefits when it comes to allergy prevention for babies at high risk of food allergy. For these babies, introducing allergens before 6 months can help prevent allergies from developing later on. That said, most families do not need to start solids before baby is developmentally ready, and for most babies this happens around 6 months of age. For more information, check out what to do if your doctor suggests starting solids early.

What do I need to do to prepare for solid food? 

Most babies start solids around 6 months of age, but it’s not too early to start preparing for the transition. Activities to get ready include:

Floor Time

Let baby play on their back, side, and tummy for playtime. Hang toys above baby’s head to encourage arm and hand movements.

Practice Grasping 

Give them lots of opportunities to hold items, drop them, and attempt to retrieve them again. Let them bring items to their mouth and explore them. 

Eat Nearby

Let baby watch you and your family eat. They can sit on your lap or in a swing or supported seat near you. At this age, babies start to learn what food is and how it works by watching you.

Oral Hygiene

Before bedtime, gently brush baby’s gums or teeth with an age-appropriate soft-bristled toothbrush, or a wet washcloth on your finger (even if teeth have not popped) to get baby comfortable with the feeling and routine.

Check out more activities to prepare for solids. 

Prepare yourself. 

Take an infant rescue course.

Get to know feeding methods to determine which feels right for you.

Start thinking about high chairs and other equipment you might want to use.
