A 3-month-old baby typically eats about 24 to 32 ounces of breast milk or formula per day, spread across 6 to 8 feedings. At each feeding, they usually consume around 3 to 5 ounces of milk or formula. Formula-fed babies often take about 4 to 6 ounces every 3 hours, while breastfed babies may take roughly 3 to 4 ounces every 2 to 3 hours during the day, with longer intervals overnight
. Feeding should generally be on demand, watching for hunger cues, and amounts can vary depending on the baby's appetite and growth spurts, which are common around 3 to 4 months. Solid foods are not recommended before about 6 months, so milk or formula remains their sole nutrition source at this age
