As a parent, you likely start thinking about your child’s nutrition from the time you start introducing solid foods. While breast milk and formula have nearly all the good stuff babies need, solid foods make things a bit trickier — but by planning well-balanced family meals, you can make sure that your little ones get all the nutrients they need to grow and thrive.
We’ve tapped three experts from our Thrive Market Nutrition & Regulatory Compliance team to better understand childhood nutrition and how to approach it at every stage of your child’s life. This handy guide will show you exactly which food groups to focus on (and which foods to avoid), whether you’re hoping to instill good nutrition habits in a toddler or to give your teen energy for school, sports, and everything in between.

While it may be difficult to adhere to exact measurements for each food group when feeding your children, it’s important to understand the general recommendations when developing a healthy routine. Starting at about 1 year old (or when babies are primarily eating solid foods), you can use these guidelines to build a balanced plate for every meal of the day.
If you struggle to meet all of these guidelines in a single day, don’t worry — there’s always time to make up for missing areas. “Your child may not eat the exact amounts suggested each day,” WIldermuth says. “It can change daily over the course of a few days or week, you just want to make sure you’re feeding a balanced diet throughout the week.”
At this stage, your baby will be trying his or her first solid foods, but breast milk or formula will still make up the majority of his or her diet.

According to the CDC, you can start to introduce solid foods when your baby exhibits these signs:
Once you determine that it’s time to start introducing solid foods to your baby, use these tips to prioritize nutrition and encourage babies to enjoy nutrient-rich foods:
Once you understand how much of each nutrient or food group your child should get in a day, it’s time to apply that knowledge to real foods. “I personally think that going by general food groups is more helpful than going by specific nutrient levels,” says Leonetti. “It’s much more practical to conceptualize 1 cup of dark green leafy vegetables as opposed to 1,000 milligrams of calcium.”
With that in mind, here are some of the most important nutrients for babies, kids, and teens — and how to ensure that yours are getting enough.
Vitamin D supports bone health and immune function, but it can be difficult to get through diet alone.
While breast milk provides just about all the nutrients babies need, it doesn’t provide enough vitamin D. Because of this, babies need 400 international units (IU) of liquid vitamin D a day until weaned or until they drink 32 ounces (about 1 liter) a day of formula with added vitamin D. “A liquid vitamin D supplement can be given directly into the baby’s mouth, or if you pump breast milk and feed via bottle, it can be given that way as well,” says Wildermuth.
“Once your baby starts solids, prioritize foods that provide vitamin D, such as egg yolks and fatty fish, like salmon,” says Wildermuth. You can also add a kid-friendly vitamin D supplement or head outside to get some sunshine, since the sun provides natural vitamin D.
Children and teens build the majority of their bone mass by the time they reach their 20s, so you’ll want to prioritize calcium intake throughout childhood and into the teen years to help build strong bones. Things like dairy milk, yogurt, leafy greens, almonds, and certain cheeses are all good sources of calcium. For children ages 1 to 8 years, aim for about 700 to 1,000 milligrams of calcium each day; for teens ages 13 to 18, aim for 1,300 milligrams.
Babies 6 to 12 months old need about 260 milligrams of calcium per day, but most receive all the calcium they need from breast milk or formula.
“Ideally, protein should be eaten throughout the day and not just at one big meal,” Wildermuth says. If you’re looking for ways to incorporate protein into your child’s diet, she recommends high-protein snack ideas like edamame, hard boiled eggs, peanut butter and whole grain crackers, lunch meat and cheese rollups, and nuts like pistachios and cashews, and yogurt.
“Infants who breastfeed typically get enough iron reserves from their mothers until about 4 to 6 months of age,” Wildermuth says. “Around this time, prioritize introducing iron-rich foods, like fortified cereal and puréed meats and beans.”
Toddlers and young children need between 7 and 10 milligrams of iron each day, and a well-balanced diet filled with iron-rich foods should help your child reach their recommended daily values for iron intake. “As your child grows older, red meat, chicken, fish, beans, and spinach are all good sources of iron,” Wildermuth says. “Serving these foods with foods rich in vitamin C, such as citrus fruits, peppers, and strawberries, can help absorption.” Teens need between 10 and 15 milligrams of iron per day, depending on gender and other factors. If your pediatrician recommends an iron supplement, you may also add in an iron supplement formulated for kids.
Potassium is another important mineral that may be overlooked in children’s diets. If your child has a potassium deficiency, you may notice symptoms like muscle weakness, vomiting, constipation, and fatigue.
Young children need between 2,000 and 2,300 milligrams of potassium per day; teens need between 2,300 and 3,000 milligrams per day, depending on gender and other factors. While most children and teens reach these amounts simply by consuming a balanced diet, you may want to prioritize potassium-rich foods like bananas, fish, meats, dried fruits, leafy greens, and dairy products if you’re concerned about your child’s potassium levels.
