Newborn formula starts small, then rises to 150–180 ml/kg per day by week two, with a daily cap near 946 ml unless your doctor says otherwise.
New parents ask this on day one, daily. How much formula in milliliters makes sense for a tiny tummy? You want a clear chart, simple math, and plain safety rules. That’s what you’ll get here. The guide below blends age based feeds, weight based totals, and real world bottle tips so you can feed with confidence.
Newborn Formula At A Glance
Babies grow fast, but the early pattern is steady. Feeds are small in the first days, then bottles scale up through the first month. Most newborns land on six to eight feeds in twenty four hours. A calm, steady rhythm keeps diapers wet, tummies content, and nights manageable. The AAP guidance on amounts notes one to two ounces per feed in week one, rising to three to four ounces by the end of month one, with a cap near thirty two ounces a day.
Use this age guide as a starting point. Watch hunger cues, stop when your baby slows or turns away, and talk to your clinician if intake seems off. The volumes below reflect standard term babies using standard formula.
Age | Per Feed (ml) | Feeds/24h |
---|---|---|
Day 1 | 5–10 | 8–12 |
Days 2–3 | 15–30 | 8–12 |
Days 4–6 | 30–45 | 7–10 |
Week 1–2 | 45–75 | 6–9 |
Week 3–4 | 75–120 | 6–8 |
How To Use This Chart Day By Day
Here’s a simple way to use the chart. Pick the age row that fits today. Check your baby’s weight to set the daily range. Divide that range by six to eight feeds to set a target per bottle. Pour a little less than the target, then top up only if cues still say “more.” This trims waste and lowers spit ups. Log feeds for three days, then look for patterns. If one slot is always short or long, adjust that slot by fifteen to thirty ml and review again.
How Many ML Formula Per Day By Weight (Newborn Chart)
After the first days, weight based math keeps bottles on track. A practical range is one hundred fifty to one hundred eighty milliliters per kilogram in twenty four hours. Many families also use the American Academy of Pediatrics rule of two and a half ounces per pound per day with a ceiling near thirty two ounces. That cap equals about nine hundred forty six milliliters. If a baby keeps crossing that line or never reaches it, call your pediatric care team.
Worked Examples
Here’s how that looks:
- Two point five kilograms: total around three hundred seventy five to four hundred fifty ml per day. Split into eight feeds, that’s about forty seven to fifty six ml each.
- Three kilograms: total around four hundred fifty to five hundred forty ml per day. Split into seven feeds, that’s about sixty four to seventy seven ml each.
- Four kilograms: total around six hundred to seven hundred twenty ml per day. Split into six feeds, that’s about one hundred to one hundred twenty ml each.
Ounce To ML Quick Map
Many tins list ounces. Here’s a quick map that keeps math easy: one ounce equals thirty milliliters. Two ounces equals sixty ml. Three equals ninety ml. Four equals one hundred twenty ml. Eight equals two hundred forty ml. If you hear a plan in ounces, multiply by thirty to get the ml you need to pour.
Signs Intake Needs A Tweak
Numbers help. Cues seal the deal. Use both.
Maybe Too Little
- Fewer than six wet diapers after day five of life.
- Hard stools or dry lips between feeds.
- Long sleepy stretches plus short bottles.
- Poor weight gain across two checks.
Maybe Too Much
- Frequent spit ups or arching near the end of feeds.
- Fast weight jumps between checks.
- Lots of gas and fuss right after big bottles.
- Baby pushes the nipple out yet milk keeps flowing.
Preparing Bottles Safely
Safe prep protects tiny guts. Wash hands, use clean bottles, and measure water first, then powder. Follow the scoop to water ratio on your brand label. Most standard powders use one level scoop for sixty milliliters of water. Warm bottles by standing them in warm water if you wish. Skip the microwave, since hot spots can burn. Start feeds within two hours of mixing, or store mixed bottles in the fridge and use within twenty four hours. Discard any leftover from a started bottle within one hour. See the CDC prep and storage rules for time limits, cooling, and cleaning details.
Powder Mixing Ratios
If your baby uses ready to feed or liquid concentrate, follow the pack steps for dilution. Do not stretch formula with extra water. That lowers calories and minerals and can be risky. If you need help with clean water or preparation, ask your health visitor or pediatric office for local guidance.
Paced Bottle Steps
Slow, steady sips match tiny tummies. Paced bottle steps keep intake smooth and comfy.
- Hold your baby mostly upright with head aligned and supported.
- Keep the bottle nearly horizontal so milk flows with baby’s sucking, not gravity.
- Let baby draw the nipple in. Touch the top lip and wait for a wide mouth.
- Offer twenty to thirty seconds of sucking, then tip the bottle down briefly to pause.
- Switch sides halfway to mirror a chest or breast feed.
- Stop when cues say so, even if a little milk remains.
Night Feeds And Sleep Windows
Night feeds matter, too. In the first weeks, many babies wake every three to four hours. Some will cluster feed in the evening. That is normal. Keep lights low, keep changes quick, and keep the same safe amounts. If your baby sleeps longer than four hours in the first month and daily totals are low, set an alarm and offer a feed.
Common Scenarios And Fixes
Bottles are not one size fits all. Small tweaks solve most bumps.
Spitting Up
Try paced feeding, hold the bottle more horizontal, and pause for burps. Smaller, more frequent bottles can help.
Gassy Baby
Use slow flow nipples, keep the head slightly higher than the tummy, and burp mid feed.
Slow Weight Gain
Confirm mix ratios, add one extra feed, and check latch on the bottle. Book a weight check.
Cluster Feeding
Evenings can be busy. Offer shorter, closer feeds while staying within daily totals.
When To Call The Doctor
No wet diaper for six hours, weak suck, repeated vomiting, fever, or breathing effort needs a prompt call.
Diaper Output And Weight Checks
Track diapers and growth to check if totals fit. Six to eight heavy wets a day and soft yellow stools suggest intake is on track in the early weeks. Your care team will watch weight on a growth chart. A tidy, steady climb beats big jumps. Bring your log to visits so tiny changes are easy to spot. Color changes day to day and can still be normal.
Sample 24-Hour Newborn Bottle Plan
Here’s a sample day once intake reaches the weight based range. Time stamps are flexible. Follow cues and your care plan.
Time | Amount (ml) | Notes |
---|---|---|
06:00 | 70–90 | Wake, diaper, quiet feed |
09:00 | 70–90 | Burp mid bottle |
12:00 | 70–90 | Short nap after |
15:00 | 70–90 | Tummy time before feed |
18:00 | 60–80 | Evening cluster start |
20:00 | 60–80 | Bath, quiet room |
23:00 | 60–80 | Dream feed if needed |
03:00 | 60–80 | Keep lights dim |
Pumped Milk Vs Formula Volume
Breast milk and standard formula both meet newborn needs. Pumped milk volumes can look smaller per feed because milk changes through the day. If you mix feeding types, use the same safe prep and storage rules for any formula bottles and offer breast on cue.
Travel And On-The-Go Tips
Out and about? Pack pre measured powder, clean bottles, and a small flask of safe hot water plus a cool bag for mixed bottles. Many parents also keep a few ready to feed bottles in the diaper bag for easy backup.
Bottle Size And Nipple Flow
Start with small bottles and a slow flow nipple (size 0–1). Milk should drip, not stream. Gulping, coughing, or five minute feeds suggest flow is too fast. Long, sleepy feeds with little progress point to a clogged vent or a nipple that’s too slow. Move up a size only when feeds still take over forty minutes despite steady effort.
Feed Logging Tips
Keep a simple log: start time, ml offered, ml taken, and short notes. A paper chart on the fridge works at three a.m. Share a photo with your care team before visits for calm, precise guidance.
Quick Reference Limits And Rules
Quick rules save time:
- Daily ceiling for most babies on formula is about nine hundred forty six ml unless your clinician sets a different target.
- Throw out any milk left in a used bottle within one hour.
- Mixed bottles can chill in the fridge up to one day. Keep them cold when you travel.
- Do not prop bottles or bottle feed while baby lies flat.
- Use only the scoop from your tin. Level it with a clean knife, not a heaped scoop.
Special Cases
Babies born early, small for dates, or with reflux, jaundice, or heart or lung conditions may follow a different plan. If your baby fits one of these groups, use this chart only as a rough frame and follow your named plan from clinic visits.
Feed charts give structure. Baby cues fill the rest. If growth and diapers look good, you’re on track. When numbers drift or something feels off, reach out. You’ve got this.
