Calculate how much formula your baby needs based on their age and weight. Get personalized feeding recommendations including daily intake, per-feeding amounts, and feeding frequency for healthy infant nutrition.
Enter 0.5 for 2 weeks, 1 for 1 month, etc.
Formula-fed babies need different amounts of milk depending on their age, weight, and individual appetite. The general guideline is approximately 2.5 ounces of formula per pound of body weight per day, but this varies by age and developmental stage.
These are average recommendations. Every baby is different, and some may need more or less than these amounts:
These calculations provide guidelines, but responsive feeding is most important. Watch for hunger cues like rooting, sucking on hands, or fussiness. Stop feeding when baby shows fullness cues like turning away, slowing down, or falling asleep.
Newborns have tiny stomachs and need frequent small feedings:
Feeding amounts increase as baby grows:
Babies settle into more predictable patterns:
Feeding amounts peak before solids are introduced:
Formula intake decreases as solid foods are introduced:
Always follow the formula manufacturer's instructions exactly:
Formula can be served at room temperature, warmed, or cold based on baby's preference. If warming, use warm water bath or bottle warmer. Never microwave formula as it creates hot spots that can burn baby's mouth. Always test temperature on your wrist before feeding.
Some babies naturally need more than average. If your baby is growing well, producing enough wet diapers, and not spitting up excessively, it's usually fine. However, ensure you're not overfeeding by mistaking other needs (comfort, sleep, diaper change) for hunger.
In the first few weeks, yes. Newborns should eat every 2-4 hours, even if it means waking them. Once baby regains birth weight and is growing well (usually by 2 weeks), you can let them sleep longer stretches at night. Always consult your pediatrician about your specific situation.
Hunger cues include rooting, sucking on hands, smacking lips, and fussiness. Fullness cues include turning away from bottle, slowing down sucking, falling asleep, or pushing bottle away. Learn your baby's unique signals.
Yes, you can switch between standard cow's milk-based formulas without gradually transitioning. However, if switching to a specialized formula (soy, hydrolyzed, etc.), consult your pediatrician first. Some babies may have temporary digestive changes when switching.
Spitting up is common and usually not concerning if baby is gaining weight well and seems comfortable. Try smaller, more frequent feedings, burp frequently, and keep baby upright after feeding. Projectile vomiting or poor weight gain requires medical evaluation.
