At 10 weeks old, most exclusively breastfed babies nurse on demand without measuring ounces, typically feeding 8-12 times per day for about 10-20 minutes per session. For formula-fed babies, a common guideline is approximately 2-3 ounces per feeding, given every 3-4 hours, totaling around 16-24 ounces daily—though individual babies vary significantly based on weight and appetite.
These amounts are general estimates; your pediatrician can provide a more precise recommendation based on your baby's weight, growth rate, and health status. Signs of adequate feeding include consistent weight gain, 6+ wet diapers daily, regular bowel movements, and contentment after feeds. Most babies at this age follow their natural hunger cues, so responsive feeding (offering food when the baby shows signs of hunger) is often more reliable than strict portion sizes.
If you're combination feeding or transitioning between breast and formula, consult your pediatrician for guidance tailored to your situation. Growth can vary widely among healthy babies, and what matters most is that your baby is gaining weight appropriately and meeting developmental milestones, not hitting a specific ounce target.
