For an 8-month-old baby, the typical amount of formula needed is about 24 ounces (approximately 720 ml) per day, divided into 4 to 6 feedings. This usually translates to about 6 to 7 ounces (180 to 210 ml) per feeding every 3 to 4 hours during the day, with no night-time feeds recommended
. More specifically:
- The University of California guidance suggests 6–7 ounces every 3–4 hours during the day, totaling 4–6 feedings daily, and recommends starting to wean from the bottle by offering formula in a cup 1–2 times per day
- The American Academy of Pediatrics recommends infants consume approximately 24–32 ounces of breastmilk or formula daily during the first year, with 4 to 5 bottles of 6–8 ounces each for babies 6 to 11 months old
- NHS guidance notes formula-fed babies may need around 600 ml of milk a day as a guide, acknowledging individual variation
- HealthyChildren.org also suggests about 24 ounces of formula daily, providing roughly 400 to 500 calories from formula or breastmilk, complementing solid foods
In addition to formula, at 8 months, babies are typically eating solid foods 3 meals and 2 snacks per day, which gradually reduces the amount of formula needed
Summary formula feeding guideline for 8-month-old baby:
- Total formula per day: ~24 ounces (720 ml)
- Number of feedings: 4 to 6 times per day
- Amount per feeding: 6 to 7 ounces (180–210 ml)
- No night feeds recommended
- Begin offering formula in a cup 1–2 times daily as weaning progresses
This schedule supports the baby's nutritional needs while complementing the introduction of solid foods.
