Key Takeaways
- Newborns eat 1–3 oz (30–90ml) per feeding, increasing to 6–8 oz (180–240ml) by 6 months
- Breastfed babies feed 8–12 times per day in the first weeks
- The best indicator is weight gain and wet diapers — not exact ounces
- Growth spurts temporarily increase feeding frequency and are completely normal
"Am I feeding my baby enough?" is the most common question new parents ask. Here's exactly how much your baby needs at every age.
Feeding Amounts by Age
| Age | Per Feeding | Feedings/Day | Total/Day |
|---|---|---|---|
| Day 1 | 0.5 oz (15ml) | 8–12 | 4–6 oz (120–180ml) |
| Day 2–3 | 0.5–1 oz (15–30ml) | 8–12 | 6–12 oz (180–360ml) |
| 1–2 weeks | 1–2 oz (30–60ml) | 8–12 | 12–24 oz (360–720ml) |
| 2–4 weeks | 2–3 oz (60–90ml) | 8–10 | 16–24 oz (480–720ml) |
| 1–2 months | 3–4 oz (90–120ml) | 7–9 | 24–32 oz (720–960ml) |
| 2–4 months | 4–5 oz (120–150ml) | 6–8 | 24–36 oz (720–1080ml) |
| 4–6 months | 5–7 oz (150–210ml) | 5–7 | 28–36 oz (840–1080ml) |
| 6–12 months | 6–8 oz (180–240ml) | 4–6 | 24–32 oz (720–960ml) + solids |
📊 These are guidelines, not rules
Every baby is different. Some take smaller, more frequent feedings. Others prefer larger, less frequent ones. Follow your baby's cues, not a strict schedule.
Breastfeeding: How to Know Baby Gets Enough
You can't measure breast milk in ounces, so look for these signs:
- 6+ wet diapers per day after day 4
- Steady weight gain — back to birth weight by 2 weeks, then gaining 5–7 oz (150–200g)/week
- Audible swallowing during feeding
- Soft, relaxed hands after feeding (clenched fists = still hungry)
- Content between feedings — not constantly rooting
Formula Feeding: Exact Amounts
The general rule: 2.5 oz (75ml) of formula per pound (0.45kg) of body weight per day, divided into feedings.
Example: A 10-pound (4.5kg) baby needs about 25 oz (750ml) per day. At 6 feedings, that's about 4 oz (120ml) per bottle.
⚠️ Don't force the bottle
If your baby turns away, pushes the bottle out, or falls asleep, they're done. Never force a baby to finish a bottle — this can lead to overfeeding.
Hunger and Fullness Cues
Early hunger cues (feed now)
- Rooting — turning head, opening mouth
- Sucking on hands or fingers
- Lip smacking
Late hunger cues (baby is very hungry)
- Fussing and squirming
- Crying (this is a late sign — try to feed before this point)
Fullness cues (stop feeding)
- Turning away from breast or bottle
- Closing mouth
- Relaxed hands and body
- Falling asleep
Feeding During Growth Spurts
Growth spurts typically happen at:
- 7–10 days
- 2–3 weeks
- 6 weeks
- 3 months
- 6 months
During a growth spurt, your baby may want to eat more frequently for 2–3 days. This is called "cluster feeding" and is completely normal. Your milk supply will adjust.
Common Feeding Concerns
Spit-up
Some spit-up is normal — most babies outgrow it by 12 months. Concern if: projectile vomiting, not gaining weight, or seems in pain.
Overfeeding
Signs: excessive spit-up, gassy/fussy after feeds, very rapid weight gain. More common with bottle feeding — pace the bottle and watch for fullness cues.
Not eating enough
Call your pediatrician if: fewer than 6 wet diapers/day, not back to birth weight by 2 weeks, or losing weight.
