How Much Formula Does Your Baby Need by Age: A Complete Feeding Guide

One of the most common questions new parents ask is, “How much formula does my baby need?” The answer changes rapidly during the first year as your little one grows. Feeding the right amount supports healthy weight gain, proper digestion, and steady development. Yet every baby is unique, so it’s important to understand general guidelines while staying attuned to your baby’s individual hunger and fullness cues.

This complete guide breaks down formula amounts by age, from the first days of life through the toddler years. Whether you’re using a cow’s milk formula like Bubs Essential Cows Milk Follow-on Formula Stage 2 or a gentle option like Bubs Easy-digest Goat Milk Follow-on Formula Stage 2, these recommendations will help you feel confident at every feeding.

Newborn to 2 Months: Small Stomachs, Frequent Feedings

During the first weeks, your newborn’s stomach is about the size of a cherry. They can only hold a small amount of milk at a time, so feedings are frequent. In the first 24 to 48 hours, babies typically take only 5 to 15 milliliters (about 1/2 to 1/2 ounce) per feeding. By the end of the first week, most infants consume 1 to 2 ounces per feeding, every 2 to 3 hours.

By the end of the first month, many babies take 3 to 4 ounces per feeding, totaling around 16 to 24 ounces per day. It’s normal for newborns to feed 8 to 12 times in 24 hours. Always watch for hunger cues like rooting, sucking on hands, or smacking lips. Crying is a late sign of hunger, so try to feed before your baby becomes overly upset.

• Start with 1–2 ounces per feeding in the first week.
• Increase to 3–4 ounces per feeding by 1 month.
• Feed on demand, typically every 2–3 hours.

2 to 4 Months: Growing Appetites and Longer Stretches

As your baby grows, their stomach expands and they can take more milk at each feeding. Between 2 and 4 months, most babies drink 4 to 6 ounces per feeding, every 3 to 4 hours. Total daily intake usually ranges from 24 to 32 ounces. You may notice your baby sleeping longer at night, perhaps 5 to 6 hours between feedings.

At this stage, some parents consider switching from a stage 1 infant formula to a stage 2 follow-on formula if their baby is ready. For example, Bubs Essential Cows Milk Follow-on Formula Stage 2 is designed for babies aged 6 months and older, so stick with stage 1 until your baby reaches that milestone. Always consult your pediatrician before changing formulas or stages.

• Offer 4–6 ounces per feeding.
• Expect 5–6 feedings per day.
• Total daily intake: 24–32 ounces.

4 to 6 Months: Preparing for Solids

Around 4 to 6 months, your baby may still take 4 to 6 ounces per feeding, but some babies increase to 6 to 8 ounces. Daily totals remain around 24 to 32 ounces. This is also the window when many babies start showing signs of readiness for solid foods, such as sitting with support and showing interest in what you’re eating.

If you’re using a gentle formula due to a sensitive tummy, a product like Bubs Easy-digest Goat Milk Follow-on Formula Stage 2 can be a great option for babies who need a softer digestion. Remember, formula should remain the primary source of nutrition until your baby is at least 6 months old. Solids are complementary, not a replacement.

• Continue with 4–8 ounces per feeding.
• Watch for signs of readiness for solids (around 6 months).
• Formula still provides most nutrition.

6 to 9 Months: Introducing Solids, Adjusting Formula

Once solids are introduced, formula intake may gradually decrease. At 6 to 9 months, babies typically drink 6 to 8 ounces per feeding, 4 to 5 times a day, for a total of 24 to 32 ounces. As your baby eats more solid foods, they may naturally drop one formula feeding. Offer formula first, then solids, to ensure your baby gets enough calories and nutrients.

For babies moving to the next stage, a follow-on formula like Bubs Easy-digest Goat Milk Follow-on Formula Stage 2 provides additional iron and nutrients to support growth. Goat milk formulas are often easier to digest for babies with mild sensitivities, making this a popular choice during the transition to solids.

• Offer 6–8 ounces per feeding.
• Reduce to 4–5 feedings per day.
• Introduce solids after formula feedings.

9 to 12 Months: Decreasing Formula, Increasing Variety

Between 9 and 12 months, your baby becomes more proficient at eating solids. Formula intake often drops to 4 to 6 ounces per feeding, 3 to 4 times a day, totaling 16 to 24 ounces. Some babies may start to show interest in whole milk after their first birthday, but it’s important to wait until 12 months to make the switch.

If your baby has a sensitive stomach, you might consider a goat milk option designed for older infants. Products like Bubs Easy-digest Goat Milk Follow-on Formula Stage 2 can be used up to 12 months, providing balanced nutrition as your baby explores new foods. Always follow your pediatrician’s advice on when to transition to cow’s milk or toddler drink.

• Offer 4–6 ounces per feeding, 3–4 times daily.
• Total daily intake: 16–24 ounces.
• Begin planning transition to whole milk or toddler formula after 12 months.

12 Months and Beyond: Toddler Nutrition

After your baby’s first birthday, whole cow’s milk or a toddler formula can replace infant formula. Most toddlers need about 16 to 24 ounces of milk per day, along with a balanced diet of solids. If your child has allergies or sensitivities, a specialized toddler drink may be a better fit. Bubs Easy-digest Goat Milk Toddler Drink Stage 3 is formulated for children 12 months and older, offering essential nutrients in a gentle, easy-to-digest formula.

Remember that every child is different. Some toddlers may drink less milk and get more calcium from yogurt, cheese, or fortified foods. The key is to offer a variety of nutritious options and let your child’s appetite guide the amount. If you have concerns about growth or feeding, consult your pediatrician.

• Switch to whole milk or toddler formula at 12 months.
• Aim for 16–24 ounces of milk daily.
• Offer a balanced diet with solids.

Feeding your baby the right amount of formula at each stage supports healthy growth and development. While these guidelines provide a helpful framework, always trust your baby’s hunger cues and consult your pediatrician with any concerns.
