A 10-month-old typically drinks 24 to 28 ounces of formula per day, split across three to four bottles of 6 to 7 ounces each. That’s less than what your baby was drinking a few months ago, and that’s exactly how it should work. As solid foods take up a bigger share of your baby’s diet, formula intake naturally decreases.
How Much Formula Per Bottle
Between 10 and 12 months, most babies drink 6 to 7 ounces per bottle, spaced about 4 to 6 hours apart. That usually means three to four bottles a day. Some babies will consistently drain 7 ounces while others hover around 5 to 6, and both are normal. The total across all bottles generally lands somewhere between 18 and 28 ounces in 24 hours, depending on how much solid food your baby eats.
This is a noticeable drop from the 32-plus ounces many babies drink at 4 or 5 months. The CDC notes that babies receiving about 32 ounces or more of formula daily don’t need additional vitamin D, which gives you a useful reference point: if your 10-month-old is still drinking that much, they may not be eating enough solids, and it’s worth looking at the overall balance.
Balancing Formula With Solid Foods
At 10 months, your baby should be eating solid foods two to three times a day plus one or two snacks, alongside their bottles. The CDC recommends offering something to eat or drink about 5 to 6 times per day at this age. That schedule typically looks like three meals of solid food and three to four bottles of formula, with some overlap.
Formula is still a critical source of calories, fat, iron, and other nutrients your baby can’t reliably get from solids alone. But the shift is real. A baby who was getting 90% of their calories from formula at 4 months might now be getting closer to half their calories from food. You don’t need to track exact percentages. The practical test is whether your baby is gaining weight steadily, eating a variety of foods, and showing interest at mealtimes.
If your baby fills up on formula right before meals, they’ll have less appetite for solids. One approach that works well: offer solids first when your baby is hungriest, then follow up with a bottle. This helps encourage the transition toward more food without cutting formula short.
Reading Your Baby’s Hunger and Fullness Cues
No chart can tell you exactly what your specific baby needs on a given day. Appetite fluctuates with growth spurts, teething, illness, and activity level. Your baby’s own signals are the most reliable guide.
Signs your baby is still hungry include reaching or pointing at food, opening their mouth when offered a spoon, getting visibly excited when food appears, and using hand motions or sounds to ask for more. Signs they’re done include pushing food away, closing their mouth when offered more, turning their head, or using gestures that signal “enough.” Forcing a baby to finish a bottle when they’re showing fullness cues can override their natural ability to regulate intake.
Water at 10 Months
Babies between 6 and 12 months can have 4 to 8 ounces of plain water per day. This is in addition to formula, not a replacement. A small sippy cup of water with meals helps your baby practice drinking and supports digestion as they eat more solid foods. You don’t need to push water aggressively at this age since formula still provides most of their hydration.
Signs Your Baby Is Getting Enough
Counting ounces is one way to gauge intake, but it’s not the only one. Steady weight gain along your baby’s growth curve is the strongest indicator that nutrition is on track. At a practical level, a baby 4 months or older who produces fewer than three wet diapers a day may be dehydrated, according to Nationwide Children’s Hospital. Most well-fed 10-month-olds produce significantly more than that.
Other reassuring signs include consistent energy during awake periods, interest in food and bottles, and normal stool patterns for your baby’s baseline. If your baby seems satisfied after feedings and is gaining weight appropriately, the exact ounce count matters less than the overall pattern.
Why Cow’s Milk Should Wait
At 10 months, you might be eyeing the milk in your fridge and wondering if you can make the switch early. The American Academy of Pediatrics recommends sticking with formula (or breast milk) as the primary liquid until your baby turns 1. Cow’s milk doesn’t have the right balance of iron and other nutrients for babies under 12 months, and it can irritate the lining of an infant’s digestive tract.
That said, there’s a small window for practice. Some pediatricians say it’s fine to offer about an ounce of whole milk in a sippy cup once a day starting around 11 months. This isn’t for nutrition. It’s to test whether your baby tolerates the taste and to build sippy cup skills before the full transition at 12 months.
A Typical Day at 10 Months
Putting it all together, a realistic feeding day for a 10-month-old might look like this:
- Morning: 6 to 7 oz bottle, followed by breakfast (soft fruit, cereal, or scrambled egg)
- Midday: Lunch of soft solids, then a 6 to 7 oz bottle
- Afternoon: Small snack, sips of water
- Evening: Dinner of soft solids, then a 6 to 7 oz bottle
- Bedtime: Optional 6 oz bottle depending on your baby’s hunger
Some babies drop to three bottles by 10 months while others still want four. Both are normal. The total daily formula intake in this example ranges from about 18 to 28 ounces, which is right in the expected range. Your baby’s appetite will guide the specifics better than any fixed schedule.
