What should I know about how much formula my baby needs?
- Understand how to estimate about how much formula your 0 to 6 month old needs per day
- Learn about how formula needs change after 6 months of age
- Know how hunger and fullness cues are an important part of how much formula your baby drinks
When it comes to feeding your baby, responding to your baby’s hunger cues and feeding on demand is best. But as parents we often want more specific guidance, especially when it comes to how many ounces of formula we should be feeding our baby each day. How much is enough? How much is too much? Let’s set the record straight.
How much formula for ages 0 to 6 months?
During the first 6 months when solid foods are not yet in the picture, there’s a simple rule of thumb to figure out how much formula your baby needs:
Here is an example for a baby who weighs ten pounds: 10 pounds x 2.5 ounces = 25 ounces total per day
2) To figure out the number of ounces per bottle, divide this number by the number of feedings your baby has in a day.
If your baby feeds 8 times per day, you would divide 25 by 8, which comes out to a little over three ounces per feeding: 25 ounces total per day / 8 feeding times per day = 3.12 ounces per feeding

Just remember, formula and/or breastmilk should remain the primary source of nutrition, with solid foods secondary to that, up until your baby is one year old.4

Formula feeding tips
Follow your baby’s hunger and fullness cues to know how much formula they need
Keep in mind, each baby is different and the above formula amounts are just averages. Babies’ appetites may change, just as ours do! Your baby may eat more or less on any given day.
By responding to your baby’s hunger cues (sucking on hands; opening and closing mouth; rooting) and fullness cues (starts and stops the feeding often; unlatching or spitting out the nipple; fidgets and is distracted; closes mouth), you will be giving your baby exactly what they need.9
Try paced bottle feeding
This method of bottle-feeding helps prevent overfeeding by putting your little one in control and allowing them to eat exactly how much they need.10 With a few simple steps, a slow-flow nipple, and a bit of practice, paced bottle feeding will come naturally to you and your little one.

How will I know baby is getting enough formula?
Your baby’s weight gain is the most important sign that your baby is getting enough formula. You’ll also want to look at diapers to know how your little one is doing.
For a newborn, look for 5 or more wet diapers and at least 1 dirty diaper per day. An older baby may have 5 or more wet diapers per day along with 1 dirty diaper every day or even every 2 to 3 days.11 Remember that every baby has a different stooling pattern, so just watch your little one’s pattern and be aware when it changes.
