At 8 weeks old, your baby is growing rapidly, and their nutritional needs continue to evolve. Feeding can feel like a full-time job during these early weeks, but understanding how much milk should an 8-week-old baby drink is essential for ensuring they are well-nourished and developing properly.
Breastfed vs. Formula-Fed Babies
One of the first considerations in determining how much milk your baby should drink is whether they are breastfed or formula-fed. Breastfed babies typically eat more frequently, as breast milk is more easily digested, while formula-fed babies may go longer between feedings.
Breastfed Babies
If you are breastfeeding, it is difficult to know exactly how much milk your baby is drinking because you cannot measure the milk intake directly. However, there are general guidelines based on the frequency and duration of feedings. On average, breastfed babies eat 8 to 12 times a day during the first few months, including at 8 weeks of age.
Each feeding can last anywhere from 10 to 30 minutes, depending on your baby’s appetite and efficiency. A well-fed baby will often appear content and satisfied after a feeding, with a regular pattern of wet and dirty diapers (at least 6 to 8 wet diapers a day). If your baby is meeting their growth milestones, it’s a good sign they are getting enough milk.
Formula-Fed Babies
If you are formula-feeding your baby, it’s easier to measure the exact amount they consume. On average, an 8-week-old baby should drink between 24 to 32 ounces of formula per day, spread out over 6 to 7 feedings. This equates to roughly 3 to 5 ounces of milk per feeding.
Most babies at this stage will signal hunger by rooting or becoming fussy, and they will stop drinking when they are full. Pay attention to your baby’s cues, as some may need slightly more or less milk depending on their size and metabolism.
Feeding Frequency and Schedule
At 8 weeks old, babies are typically fed every 2 to 4 hours, whether breastfed or formula-fed. While some babies may start sleeping for longer stretches at night, many still wake up for at least one night feeding.
Daytime Feedings
During the day, feedings will likely be more frequent. Breastfed babies may nurse more often to keep up with their rapid digestion, while formula-fed babies might have a more predictable schedule.
If your baby is consistently fussy or waking up frequently, they might be experiencing a growth spurt. Around 6 to 8 weeks, babies often go through a period of increased hunger, leading to more frequent feedings.
Nighttime Feedings
By 8 weeks, some babies may start sleeping for longer stretches during the night, but most will still wake up for a feeding or two. Formula-fed babies may go longer between night feedings because formula takes longer to digest, but it’s normal for breastfed babies to wake up every few hours to eat. As your baby grows, they will gradually start sleeping longer at night and eating more during the day.
How to Know If Your Baby Is Getting Enough Milk
Worrying about whether your baby is getting enough milk is common among new parents, especially if you are breastfeeding and cannot measure the intake. Here are some signs that your baby is getting the right amount of milk:
Weight Gain
One of the clearest indicators that your baby is getting enough milk is steady weight gain. At regular check-ups, your baby’s pediatrician will track their weight to ensure they are growing at a healthy rate. By 8 weeks, most babies should gain around 5 to 7 ounces per week.
If your baby is consistently gaining weight within this range, it’s a good sign that they are getting enough milk.
Diaper Output
Another reliable indicator is your baby’s diaper output. A well-fed baby will produce at least 6 to 8 wet diapers per day. Breastfed babies may have more frequent bowel movements, often after every feeding, while formula-fed babies may have fewer but still regular dirty diapers.
If you notice fewer wet diapers or a significant change in your baby’s stool, it might be worth checking with your pediatrician to ensure they are getting enough to eat.
Contentment After Feeding
A content baby is another sign that they are getting enough milk. After a feeding, your baby should seem relaxed, with loose fists and a calm demeanor. If your baby is still fussy or rooting after feedings, they may need more milk.
However, fussiness doesn’t always indicate hunger. It’s essential to consider other factors like sleep or comfort needs.
Factors That Affect Milk Intake
Several factors can influence how much milk an 8-week-old baby needs, including their size, metabolism, and growth rate. Here are a few key factors to keep in mind:
Growth Spurts
Around 8 weeks, many babies experience a growth spurt, which can lead to increased hunger and more frequent feedings. During this time, your baby may seem to cluster feed, particularly if you are breastfeeding.
While this can be exhausting, it is usually temporary and a sign that your baby is growing. The growth spurt may last a few days to a week, after which your baby may return to their regular feeding pattern.
Baby’s Size
Larger babies often need more milk than smaller babies. If your baby was born with a higher birth weight, they might consume more milk than the average 8-week-old. Conversely, smaller babies may need slightly less milk but will still eat frequently to keep up with their rapid growth.
Activity Levels
Some babies are more active and alert than others, which can also affect how much milk they need. Babies who are awake and moving around more may burn more calories, requiring additional milk to meet their energy needs.
More relaxed or sleepy babies may not need as much milk but will still require regular feedings to support their growth and development.
Tips for Feeding an 8-Week-Old Baby
Feeding an 8-week-old baby can feel like a constant task, but these tips can help make the process smoother:
Follow Your Baby’s Cues
Every baby is different, and it’s essential to pay attention to your baby’s hunger and fullness cues rather than sticking to a rigid feeding schedule. If your baby is rooting, sucking on their hands, or becoming fussy, they may be hungry. If they turn away from the bottle or breast or seem content, they are likely full.
Keep Track of Feedings
For both breastfed and formula-fed babies, keeping track of feedings can help ensure your baby is eating enough. Apps or simple notepads can help you record feeding times, durations, and amounts, giving you peace of mind that your baby is getting the nutrition they need.
Don’t Force Feedings
It’s normal to worry if your baby isn’t finishing a bottle or seems to be eating less at times, but it’s essential not to force feedings. Babies are good at self-regulating and will eat when they are hungry.
If your baby is refusing milk or showing disinterest in feeding, give them a break and try again later.

Conclusion
At 8 weeks old, your baby is going through a period of rapid growth, and their milk intake will vary based on factors like whether they are breastfed or formula-fed, their size, and their activity level. Most babies will drink between 24 to 32 ounces of milk per day, with breastfed babies eating more frequently. By paying attention to your baby’s hunger cues, diaper output, and weight gain, you can ensure they are getting enough milk to thrive.
