A 10-month-old typically needs 6 to 7 ounces of formula per feeding, spread across 3 to 4 feedings per day. That works out to roughly 18 to 28 ounces total in 24 hours, depending on how much solid food your baby is eating. The upper limit to keep in mind is 32 ounces per day, which is the maximum most babies should consume.
Daily Formula Amounts at 10 Months
At this age, feedings are spaced about 4 to 6 hours apart, and most babies have settled into a predictable rhythm of 3 to 4 bottles (or cups) per day. Nighttime feeds are no longer necessary for a healthy 10-month-old, so all formula intake happens during waking hours.
Here’s what a typical day looks like:
- Per feeding: 6 to 7 ounces
- Number of feedings: 3 to 4
- Total daily intake: roughly 18 to 28 ounces
- Maximum in 24 hours: 32 ounces
Your baby’s exact intake will vary from day to day. Some days they’ll drain every bottle, and other days they’ll lose interest halfway through. That’s normal. What matters is the overall pattern over a week, not any single feeding.
Balancing Formula With Solid Foods
Formula is still the main source of nutrition for babies under 12 months, but at 10 months, solid foods are making up a bigger share of your baby’s diet than they were a few months ago. Most 10-month-olds eat solid foods 2 to 3 times a day alongside their formula feedings, totaling about 5 to 6 eating occasions in 24 hours when you count both formula and solids together.
As your baby eats more solids, their formula intake naturally drops. A baby who was drinking 30 ounces at 6 months might now be closer to 22 or 24 ounces simply because they’re getting more calories from table food. This gradual shift is exactly what should be happening. If your baby is consistently hitting the 32-ounce ceiling and also eating solids, they may be taking in more than they need, which can set the stage for patterns of excess weight gain even in infancy.
How to Tell if Your Baby Is Getting Enough
Rather than obsessing over exact ounce counts, watch your baby’s hunger and fullness cues. At 10 months, these are much clearer than they were in the newborn days. A hungry baby will reach for food, open their mouth when offered a spoon or bottle, and get visibly excited at the sight of food. They may also use hand motions or sounds to tell you they want more.
When your baby is full, the signals are just as obvious: pushing food or the bottle away, closing their mouth when you offer more, or turning their head to the side. Respecting these cues helps your baby develop healthy self-regulation around eating. If you consistently push extra ounces after they’ve signaled they’re done, you override that internal system.
Hydration is another useful check. A well-fed baby produces plenty of wet diapers throughout the day. Signs of dehydration to watch for include fewer wet diapers than usual, a sunken soft spot on top of the head, few or no tears when crying, sunken eyes, or unusual drowsiness and irritability.
Why 32 Ounces Is the Upper Limit
Drinking more than 32 ounces of formula a day can crowd out solid foods, which means your baby misses out on the iron, zinc, and other nutrients that formula alone doesn’t provide in sufficient amounts for this age. It can also mean excess calorie intake. If your baby regularly exceeds 32 ounces while also eating solid meals, it’s worth adjusting the schedule so solids get more of a spotlight.
On the flip side, a baby who’s barely drinking 16 ounces and isn’t eating much in the way of solids either may not be getting enough overall nutrition. Steady weight gain on their growth curve and consistent wet diapers are the best real-world indicators that intake is on track.
Offering Formula in a Cup
Ten months is a good time to start offering some formula in an open cup or a straw cup rather than exclusively in bottles. This isn’t about taking bottles away overnight. It’s about giving your baby practice with cup drinking so the transition away from bottles (which pediatricians generally recommend by 12 to 18 months) isn’t a sudden shock. You might offer one feeding per day from a cup and keep bottles for the rest.
Preparing for the Switch to Milk
At 10 months, you’re about two months away from the typical transition to cow’s milk, which happens after the first birthday. There’s no need to introduce cow’s milk as a drink yet, but it helps to know what’s ahead.
If your baby is eating a nutritionally balanced diet of solids by age 1, you can begin weaning off formula at that point. The simplest approach is to start offering 2 to 4 ounces of whole milk for every two or three servings of formula, then gradually increase the milk and decrease the formula over a week or so. If your baby isn’t a fan of the taste, you can mix a small amount of milk into a prepared formula bottle (for example, 3 ounces of formula and 1 ounce of milk in a 4-ounce bottle) and slowly shift the ratio.
Some babies develop signs of cow’s milk intolerance during the transition, including constipation, diarrhea, rash, or vomiting. If that happens, slow down and give their system time to adjust. Babies who aren’t gaining weight well, haven’t established a solid food diet, or have certain health conditions like food allergies or kidney or liver issues may need to stay on formula longer.
