“How much milk should my baby be drinking?” is one of the most common questions new parents ask — and one of the most confusing. The answer changes every few weeks, and breastfed and formula-fed babies have slightly different patterns. This guide gives you clear, age-by-age targets for milk intake from birth through 12 months, plus how to tell if your baby is getting enough.
These numbers are guidelines, not strict rules. Babies are individuals. Always pair these targets with your pediatrician’s advice and your baby’s growth curve.
📌 Key Takeaway: According to the American Academy of Pediatrics (AAP), most healthy infants need 2-2.5 oz of formula per pound of body weight per day. This guide gives you evidence-based, practical guidance you can apply today. For a related deep dive, see our guide on how many naps by age.
The General Rule for Formula
A widely used pediatric formula for daily formula intake is:
2 to 2.5 ounces of formula per pound of body weight per day, up to about 32 ounces per day.
For example, a 10-pound baby would need about 20–25 oz of formula per day, divided into 6–8 feeds. After about 6 months, total daily volume usually plateaus around 24–32 oz as solid foods take over.
Breastfeeding Is Different
Breastfed babies regulate their own intake, so we measure feeding by frequency and signs of fullness rather than ounces. On average, exclusively breastfed babies consume about 24–32 oz of breast milk per day from 1 to 6 months — surprisingly stable across that range.
Daily Milk Intake by Age
The chart below combines breastfeeding and formula guidance:
| Age | Total daily milk | Per feed (formula) | Feeds per day |
|---|---|---|---|
| 0–1 month | 16–24 oz | 1.5–3 oz | 8–12 |
| 1–2 months | 22–28 oz | 3–4 oz | 7–9 |
| 2–4 months | 24–32 oz | 4–6 oz | 6–8 |
| 4–6 months | 28–32 oz | 6–8 oz | 5–6 |
| 6–8 months | 24–32 oz | 6–8 oz | 4–5 + solids |
| 8–10 months | 20–28 oz | 6–8 oz | 3–5 + solids |
| 10–12 months | 16–24 oz | 6–8 oz | 3–4 + solids |
| 12+ months | 16–24 oz whole milk | n/a | 2–3 + solids |
Newborn (0–1 Month)
Newborn stomachs are tiny. On day 1, baby’s stomach holds only about 5–7 mL — less than a teaspoon. By day 10, it can hold 60–80 mL (2–3 oz).
- Feed every 2–3 hours, including at night
- 8–12 feeds per 24 hours is normal for breastfed babies
- Watch for hunger cues: rooting, lip smacking, hand-to-mouth, fussiness
- Aim for 6+ wet diapers and 3–4 stools per day after day 5
Wake your newborn to feed if they sleep more than 4 hours during the first 2 weeks. After regaining birth weight, you can let them sleep longer stretches if their pediatrician approves.
1–2 Months
Baby’s stomach has grown to handle 3–4 oz per feed. You may notice:
- More predictable feeding intervals (every 2.5–3.5 hours)
- Longer night stretches starting (4–6 hours)
- A growth spurt around 6 weeks with cluster feeding
Don’t panic during cluster feeds — this is how baby signals supply to increase. It usually settles within a few days.
2–4 Months
Many babies hit their peak daily volume here, around 28–32 oz. Feeding becomes more efficient — what used to take 30 minutes might now take 10–15.
A second growth spurt often hits around 3 months. You may also see distractibility — baby pops on and off, gets fussy at the breast or bottle. This usually passes within a week or two.
4–6 Months
Daily intake plateaus or slightly decreases. Some babies start showing readiness for solids by 6 months, but milk should still be the main source of nutrition.
Avoid:
- Putting cereal in bottles (choking risk, and not effective for sleep)
- Forcing extra ounces “for sleep” — overfeeding causes spit-up and discomfort
- Switching formulas without medical reason
6–9 Months: Adding Solids
Once solids start, milk volume gradually decreases as solid food calories ramp up. Aim for:
- 24–32 oz of milk total
- 1–3 small solid meals per day
- Continue offering milk before solids in early months, then alongside
For more on starting solids, see our starting solids at 6 months guide.
9–12 Months
By 12 months, milk drops to roughly 16–24 oz per day, with solids covering the bulk of nutrition. Babies are usually eating 3 meals plus 1–2 snacks.
This is also the time to start practicing with an open or straw cup, in preparation for transitioning off bottles. Our weaning from bottle to sippy cup guide walks through that transition.
After 12 Months
Switch to whole cow’s milk (or a fortified plant milk under pediatric guidance). The AAP recommends:
- 16–24 oz of whole milk per day from 12–24 months
- No more than 24 oz/day — too much milk crowds out iron-rich foods and can cause anemia
- Move from bottles to cups before 18 months
Signs Baby Is Getting Enough
Numbers are a guide. Real evidence comes from baby’s behavior and growth:
- Weight gain following their growth curve
- 6+ wet diapers per day after week 1
- Regular stools (frequency varies by age)
- Alert, content between feeds
- Reaches developmental milestones on schedule
If you are unsure, weight checks with your pediatrician are the gold standard.
Signs of Underfeeding or Overfeeding
Underfeeding signs
- Fewer than 6 wet diapers/day after week 1
- Poor weight gain
- Lethargy, weak cry
- Sunken fontanelle, dry mouth
Overfeeding signs
- Frequent forceful spit-up
- Excessive gas, fussiness right after feeds
- Weight gain well above the curve in the early months
- Refusing the bottle then taking it again
Common Mistakes
- Forcing baby to finish bottles — leads to overfeeding and spit-up
- Watering down formula — dilutes nutrition; never do this
- Switching formulas at the first sign of fussiness — most fussiness is unrelated to formula
- Ignoring fullness cues like turning the head, pushing the bottle, sealing lips
Frequently Asked Questions
How do I know how much milk a breastfed baby is getting?
You don’t need exact ounces. Track wet/dirty diapers, weight gain, and fullness cues. If your pediatrician is happy with growth, your baby is getting enough.
My 4-month-old is drinking less. Should I worry?
Some babies plateau around 24–28 oz. As long as growth is on track and behavior is normal, this is fine. Talk to your pediatrician if intake drops suddenly.
Can I overfeed a breastfed baby?
It is very rare. Babies self-regulate at the breast. Overfeeding is much more common with bottles, where it is easy to push baby past their natural fullness signal.
How long should bottle feeds take?
A typical bottle feed lasts 15–25 minutes. Faster than 5 minutes may mean the nipple flow is too fast; longer than 30 may mean baby is not actively feeding or the flow is too slow.
When should I drop a feeding?
Most babies naturally drop the night feed first, then a daytime feed once solids are well established. Follow your baby’s lead — if they consistently take less at a feed, it may be ready to go.
