Portion Sizes for Kids by Age: A Simple Chart for Ages 1 to 8

A toddler's serving is about a quarter of an adult's, according to the American Academy of Pediatrics (AAP), and a serving of cooked vegetables is about 1 tablespoon per year of age. Below, we pair that with daily servings from Healthy Eating Research (HER) for ages 2 to 8.

TL;DR
  • A toddler serving is about ¼ of an adult's; cooked vegetables, about 1 tbsp per year of age.
  • Intake swings from day to day, so look at the whole week, not one meal.
  • Offer food and let your child decide how much; call the doctor if they don't gain weight as expected.

Portion sizes by age: the chart

These are amounts to offer, not to finish, and they vary "with each child's build and activity level" (AAP).

One serving for ages 1 to 3 from the AAP (column 1). Servings per day for ages 2 to 8 from Healthy Eating Research (columns 2 to 4).
Food group1 to 3 years: one serving (AAP)2 years per day (HER)3 to 4 years per day (HER)5 to 8 years per day (HER)

  • Units: 1 tablespoon is 3 teaspoons (15 mL); 1 cup is 8 ounces (240 mL) (AAP).
  • Adding it up: at age 2, 4 to 8 quarter-cups of vegetables works out to 1 to 2 cups a day. That total is our arithmetic, not a number HER prints.
  • The tablespoon rule: the AAP gives it for cooked vegetables. Nationwide Children's uses it for fruits too.

Seeing what your child actually ate

The chart tells you what to offer, not what went in. In Sito you log a meal and can change a food's amount, in cups or tablespoons where the food offers them.

  • How much came back? Enter the percent left on the plate, for the whole meal or per food, and we count only what was eaten.
  • Today or the week: the dashboard shows the day against your child's goal ranges, or a 7-day average. Under 2, we note that toddler appetites swing and point you to that average.
  • Your doctor's number: if a doctor or dietitian gave you a calorie goal, enter it and we use yours instead of our estimate.

Sito does not count food-group servings or compare a plate to this chart. For a paper record, see our printable food diary for kids.

See what your child actually ate

Log a meal by photo, barcode or search, mark how much came back, and see today next to the 7-day average.

How much should kids drink?

Sources differ slightly on milk: about 2 cups (16 oz) a day for toddlers, with an upper limit of 2 to 3 cups depending on source and age. Juice for toddlers: no more than 4 oz (half a cup) a day.

Drinks per day. Ages 1 to 5 from the AAP and the 2019 HER consensus; ages 5 to 8 from HER 2025.

What a toddler plate looks like

The AAP's average toddler meal is about 1 oz of meat or 2 to 3 tbsp of beans, 1 to 2 tbsp each of vegetables and fruit, and ¼ slice of bread (AAP). A sample from the Academy of Nutrition and Dietetics (eatright.org):

  • 4 tbsp cooked pasta
  • 2 tbsp ground meat
  • 1 tbsp cooked green beans
  • ¼ cup canned fruit
  • ½ cup whole milk

12 to 24 months. HER lists, per meal or snack: ¼ to ½ cup vegetables, ¼ to ½ cup fruit, ½ to 1 oz protein ("about the size of 3 dice"), and ½ to 1 slice of whole grain bread or ¼ to ½ cup whole grain cereal or pasta.

Ages 3 to 5. Meat "about the size of the child's hand or about 2 ounces" (eatright.org).

For 1-year-olds, the AAP says anything you give should be "mashed or cut into small, easily chewable pieces" (AAP).

Why your child eats a lot one day and little the next

After the first birthday, growth slows. The AAP says you'll probably notice "a sharp drop" in appetite, because your child "really doesn't require as much food now" (AAP).

  • Toddler eating is "erratic and unpredictable from one day to the next." A toddler may eat everything at breakfast and almost nothing after (AAP).
  • For weeks, some toddlers eat only 1 or 2 preferred foods (AAP). If it's vegetables, see what to do when a toddler refuses vegetables.
  • From around 12 months, a child "might even go a couple days without eating much," and "over a week, your child should get all the foods and nutrients they need" (CDC).

In the NHS's words: "If your child is active and gaining weight, and they seem well, then they're getting enough to eat" (NHS).

Let them decide how much

"It's a parent's responsibility to provide food, and the child's decision to eat it" (AAP). Pressure or punishment can make children actively dislike foods.

  • Skip the clean plate. Don't expect children to "clean their plates" (AAP) or pressure them to finish (HER).
  • Drop "just one more bite." It encourages children "to ignore their own hunger and fullness cues" (eatright.org).
  • Use small dishes. The AAP suggests smaller plates, bowls and cups (AAP).
  • Read the signals. Full toddlers may "push food away, close their mouths or turn their heads away" (KidsHealth).

How many calories is that?

The National Academies' 2023 estimates for US children of median size (NASEM):

AgeBoys (kcal/day)Girls (kcal/day)
12 to 14 months821780
24 to 26 months1,0581,011
3 years1,078 to 1,2451,075 to 1,217
5 years1,318 to 1,5671,241 to 1,517
8 years1,700 to 2,0861,470 to 1,896

Ranges run from inactive to very active. A child's actual need "may vary considerably" from these estimates, which aren't designed for weight goals. Children "should not be on calorie-restricted diets unless recommended by a doctor" (AAP).

The calculator above gives the NASEM estimate for your child. More in calorie trackers for kids.

Older kids and teens

MyPlate's age pages now redirect to its homepage, which points to the new Dietary Guidelines (MyPlate, checked September 2026). Their serving table goes by calorie level (1,000 to 3,200), not age, and says "smaller portions may be appropriate" for young children (USDA).

For median-size 13-year-olds, NASEM estimates 2,482 to 3,205 kcal a day for boys and 2,017 to 2,648 for girls.

When to talk to the doctor

KidsHealth's reasons to call your doctor include when your child (KidsHealth):

  • develops new symptoms like vomiting, diarrhea or fever
  • doesn't begin to gain weight as expected
  • is tired a lot or doesn't have the energy for everyday activities
  • misses developmental milestones like sitting up, walking or talking

Go to the ER if your child is vomiting over and over, isn't drinking at all, or shows signs of dehydration: a dry or sticky mouth, sunken eyes, less or darker pee than usual, few or no tears, or unusual sleepiness (KidsHealth).

If your toddler mostly wants milk, the AAP suggests seeing your pediatrician if that doesn't change within a month of following its advice, or if they don't eat many more solids after about 2 months (AAP).

Picky eating "usually is a normal developmental stage for toddlers" (AAP). If you're worried, ask your pediatrician and a pediatric registered dietitian nutritionist (eatright.org). If weight gain is the worry, see when a toddler isn't gaining weight and high-calorie foods for toddlers.

Frequently asked questions

How much should a 2-year-old eat?

The AAP's typical daily menu for a 2-year-old includes 2 to 2½ cups of dairy, 2 to 3 servings of grains, 1 cup each of fruit and vegetables, and 1½ to 2 oz of protein. NASEM estimates 1,058 kcal a day for a median-size boy at 24 to 26 months and 1,011 for a girl.

My toddler skipped dinner. Is that OK?

KidsHealth says to expect a toddler to "sometimes eat less or skip meals." Toddler eating is erratic from day to day (AAP), and over a week your child should get all the foods and nutrients they need (CDC). If your child doesn't gain weight as expected, call your doctor.

How much milk should a 2-year-old drink?

The AAP lists 16 to 24 oz (2 to 3 cups) of nonfat or low-fat milk a day for ages 2 to 5. A 2019 consensus of four health groups, including the AAP, puts it at 2 cups or less for ages 2 to 3.
