After baby turns one, they can start drinking milk. But how much is the right amount—and what are the signs of too much? Here’s what you need to know!


Milk for One Year Olds

The American Academy of Pediatrics recommends these amounts for toddlers and milk consumption:

  • 12-24 months: 16-24 ounces or 2-3 8-ounce cups per day
  • 2-5 years: 16-20 ounces or 2- 2.5 8-ounce cups per day

TIP: You want to move these milk amounts to be served with meals as you continue to get your one year old onto the same general eating schedule as the rest of the family, with the goal of being done with bottles by 18-24 months.

Transitioning to Cow’s Milk

If you’re moving from breastmilk to cow’s milk, you can simply start serving a small amount with meals. (Start with 1 ounce to let the kiddo adjust to the flavor and avoid wasting the milk if they don’t love it.)

If moving from formula to cow’s milk, you can start replacing 1 ounce of the prepared formula with milk at a time, until you have the full amount replaced with milk.

TIP: It’s normal for some kids to not love the flavor of milk right away (or ever). Remember that milk is just one food in a big category of dairy and it’s possible to offer other foods rich in calcium, protein, and Vitamin D.

Transitioning to a Sippy Cup from a Bottle

The AAP recommends that we start to move away from bottles by no later than 18 months (if not sooner) and I’ve found that it can help to make a big deal out of the new milk cup to help the kids through this transition.

Remember that weaning from a bottle is emotional as it’s been a source of comfort, so be patient and consistent. It’s normal for the kids to have feelings about this.

Best Non-Dairy Milk for Toddlers

If you have a kiddo who’s allergic to cow’s milk or needs non-dairy milk for another reason, you’ll want to look for ones with similar nutrition as cow’s milk.

Options for nondairy milk that have fat, protein, and vitamin D include soy milk and plant milk made with pea protein (such as Ripple Milk and Silk Nut Protein Milk).

There are many other options of nondairy milks, though often almond, rice, and oat milk don’t have fat or protein. There is a big variety of nutrition in these (since there are SO many options now), so check the label.

I also recommend choosing a plain, unsweetened nondairy milk without added sugar if possible. (Cow’s milk has sugar, but it’s naturally occurring and doesn’t taste as sweet as many nondairy milks with added sugar do.)

Frequently Asked Questions

What if my toddler doesn’t like milk?

If your toddler doesn’t like milk, simply aim to offer 2-3 servings of other dairy products each day to help them eat the RDA for calcium. Many kids don’t love milk and it’s totally fine. (You can also consider these Flavored Milks.)

My toddler only wants milk, not food. What should I do?

If milk consumption is interfering with intake of solid food—whether the milk is cow’s milk, nondairy milk or breastmilk—you can consider reducing the amount of milk offered throughout the day. It’s possible the child is simply full from milk and has little incentive to eat solids.

How much milk is too much for one year old?

The American Academy of Pediatrics recommends an upper limit of 24 ounces for one year olds. For some kids with smaller appetites, that amount of milk may lead to less hunger for solids, so you can drop the amount down to the lower end of the range at 16 ounces.

Many little kids don’t drink a full 8 ounces in once sitting, so 2-3 smaller 4 ounce servings is also very reasonable for a one year old.

Toddler Formula and Toddler Milk

Does my one year old need “toddler formula”, “toddler milk”, or “kids milk”? No, unless there’s a medical reason and a doctor has specifically recommended these products, there is no nutritional reason to offer these fortified milks.

(They are often more expensive than regular milk too.)

Best Tips for One Year Olds and Milk

  • For kids 12-24 months, keep milk in the 16-24 ounces a day range.
  • For kids 2-5 years, keep milk in the 16-20 ounces a day range.
  • Aim to start transitioning away from the bottle and towards a sippy cup by no later than 18 months.
  • If a child doesn’t like milk or drinks less than that, know that it’s 100% okay and they can meet the recommendations for calcium from eating other dairy products including cheese, yogurt, cottage cheese, and kefir.
  • For nondairy kiddos, look for unsweetened plain milks with fat and protein (for similar nutrition to cow’s milk) in soy milk and plant milk fortified with pea protein.
  • Toddler formula, toddler milk, kids milk, and growing milks are not nutritionally required for little kids.

  1. My baby has refused to eat any meal given to him I need a help please, he’s two years old and he’s slimming.

    1. If the child is refusing all food and losing weight, please consult with your doctor. You may need medical advice and/or a feeding therapist.

  2. Hello! Is the ounces per day recommendation the same if it is breast milk? I have a 12 month old and I’m transitioning her from nursing to cups with straws but still using breastmilk. Curious to know if it’s an equivalent recommendation. Thanks!

    1. Hi- Generally speaking, I believe it would be the same for any type of milk you’re serving in a cup since the goal with that upper limit is to avoid the kiddo filling up on milk and having less room for other solids (and other nutrients). The thing that different about breastmilk as you likely know is that the nutritional composition changes as baby grows so that part would be different from cow’s milk. I hope that helps!
