At 12 months, a breastfed baby typically drinks around 600 mL (about 20 ounces) of breastmilk per day. That number can vary quite a bit depending on how much solid food your child eats, but it gives you a reliable ballpark. The bigger shift happening at this age is that solids are becoming a major part of your child’s diet, and breastmilk is gradually moving from the main course to a important supplement.
Typical Daily Intake at 12 Months
Studies of healthy, breastfed infants show an average intake of about 593 mL per day at 12 months, which works out to roughly 20 ounces. That’s noticeably less than what most babies drink at 3 or 6 months, when breastmilk is their sole or primary food source. The decline is normal and expected as solids take on a bigger role.
Unlike formula feeding, where you can measure bottles precisely, breastfeeding intake is harder to track. Some 12-month-olds nurse frequently and get closer to 24 ounces a day. Others, especially enthusiastic eaters who love solid food, may only nurse a few times and take in 16 ounces or less. Both patterns fall within a healthy range as long as your child is growing well.
How Many Nursing Sessions to Expect
There’s no single correct number of nursing sessions at this age. Some toddlers want to breastfeed only in the morning and before bed, while others continue nursing several times throughout the day. The CDC recommends following your child’s hunger cues rather than sticking to a rigid schedule.
A common pattern is 3 to 4 nursing sessions spread across the day, often tied to wake-up, nap times, and bedtime. Each session at this age typically lasts shorter than it did in earlier months, since toddlers are more efficient at the breast and also more easily distracted. If your child nurses more or less often than this, that’s fine. The key is whether they’re also eating solid foods and gaining weight appropriately.
Balancing Breastmilk and Solid Foods
At 12 months, your child should be eating three meals and two to three snacks each day, with something to eat or drink roughly every 2 to 3 hours. Before this point, breastmilk was the main source of nutrition with solids as a complement. Around the first birthday, that relationship flips. Solid foods become the primary source of calories and nutrients, and breastmilk fills in the gaps.
A practical way to structure the day is to offer solid food first at mealtimes, then nurse afterward if your child is still hungry. This ensures they’re getting enough variety from food (especially iron-rich options like meat, beans, and fortified cereals) while still benefiting from breastmilk’s nutrition. If you nurse right before a meal, some toddlers fill up on milk and then refuse the food they need.
That said, there’s no reason to force a strict order. Some families find that nursing on demand alongside regular meals works perfectly well. The goal is simply making sure breastmilk isn’t crowding out solid foods so completely that your child misses key nutrients like iron and zinc, which breastmilk alone doesn’t provide in sufficient quantities at this age.
How Long to Keep Breastfeeding
The World Health Organization recommends continuing breastfeeding up to two years of age or beyond, alongside solid foods. Breastmilk at 12 months and beyond still provides fat, protein, antibodies, and other immune factors that benefit your toddler. It doesn’t lose its value after the first birthday.
If you’re planning to wean, there’s no medical deadline that says you must stop at 12 months. And if you want to continue, the frequency will likely decrease naturally as your child eats more food and becomes more independent. Many toddlers self-wean between 12 and 24 months simply because they’re getting most of their nutrition from the table.
What About Cow’s Milk or Water?
At 12 months, cow’s milk becomes an option if you want to introduce it. The general guideline is to keep cow’s milk to no more than about 500 mL (roughly 16 ounces) per day. Drinking more than that can interfere with iron absorption and reduce your child’s appetite for solid foods, increasing the risk of iron deficiency anemia. If your child is still breastfeeding regularly, they may not need cow’s milk at all, or may only want small amounts.
Water is also appropriate to offer at meals and snacks. Between 6 and 12 months, the CDC suggests 4 to 8 ounces of water per day. After 12 months, your child can drink water more freely, especially as they eat more solid foods. Breastmilk still contributes to hydration, so a nursing toddler typically needs less additional water than one who has fully weaned.
Signs Your Child Is Getting Enough
Since you can’t measure what comes out of the breast the way you can measure a bottle, look at your child instead of trying to count ounces. Between 6 and 12 months, healthy weight gain averages 1.5 to 3 ounces per week. After the first birthday, growth slows down further, and that’s normal.
Consistent weight gain along their growth curve is the most reliable sign that intake is adequate. Other reassuring signals include regular wet diapers (at least 4 to 6 per day), energy and alertness during awake periods, and steady developmental progress. If your child is active, eating a variety of solids, nursing several times a day, and tracking along their growth curve, their breastmilk intake is almost certainly sufficient, even if you have no idea how many ounces that actually is.
