General eating schedule. However, breastfed babies drink 1-1.5 oz per hour. A 19-36 oz day is normal range. That being said, 7, 3oz bottles in a day instead of the 5-6 oz bottles shown here is normal. Even at 10 months, my child drinks 2-3 oz every 2-3 hours and will consume approx 21oz in a 24 hr period; also eating solids since 4 months of age.
