Drinking Milk Is Still Recommended for Kids

Child Nutrition Basics

Whether it is an infant who is drinking breast milk or an iron-fortified baby formula that is based on cow's milk or soy milk, a preschooler drinking chocolate milk, or a teenager drinking low fat milk, milk is an important part of child nutrition. After all, milk has even had its own food group.

In addition to providing children with a variety of vitamins, minerals, and other nutrients to keep kids healthy, milk is especially important to help build and maintain strong bones.

Types of Milk

Although most parents think of cow's milk when they think of milk, there are actually a wide variety of milk and other non-dairy milk drinks that can usually substitute for milk.

The different types of "milk" that kids might drink include:

Some people are even drinking hemp milk these days.

Milk Nutrition

Many kids don't drink enough milk, which is unfortunate, because fortified milk is a good source of many important vitamins, minerals, and other nutrients.

Milk is usually considered a key part of a healthy diet for kids, as it provides those children with a good source of:

Also, kids who drink milk are not as likely to drink other less nutritious drinks, such as soda and fruit drinks.

Keep in mind that if you are giving your kids a non-dairy milk drink, you should be sure to check the label to make sure it is fortified or enriched with all of these vitamins and minerals.

Milk Recommendations

In general, toddlers should drink whole cow's milk if they don't have a milk allergy after they are 12 months old. They should then switch to reduced fat milk once they are two years old. Overweight toddlers can switch to low-fat milk even earlier though, after their first birthday.

Keep in mind that toddlers who are breastfeeding two to three times a day or who are still drinking a toddler formula don't necessarily also need to drink milk. They do likely need extra vitamin D though if they are breastfeeding and not getting vitamin D from another source.

How much milk do your kids need?

It depends on how old they are, but the the usual recommendations are that children who are:

  • 2-8 years old drink 2 cups of milk each day
  • 9-18 years old drink 3 cups of milk each day

Of course, if your kids don't drink milk, you can substitute other things from the dairy food group, such as cheese and yogurt or other foods high in calcium and vitamin D.

Even if your kids (over age 12 months) do drink milk, they will likely also need to eat some other foods that are rich in calcium and vitamin D to reach the latest recommended daily allowance of 600 IU per day for vitamin D.

Drinking too much milk isn't a good idea though. In addition to the extra calories, drinking too much milk is a risk for iron deficiency anemia.

Calories from Milk

Getting too many calories is a problem for many overweight kids. In addition to getting enough physical activity each day, these children often need to decrease their portion sizes and cut back on some calories.

Eliminating milk because of the worry about the calories in milk is usually not a good idea though. Instead, you should switch your child from whole milk to low-fat or reduced fat milk.

A quick comparison of milk nutrition labels (per 8 ounce serving) shows how many calories your kids will get from drinking each type of milk:

  • Whole Milk - 150 Calories - 8g Fat
  • 2% Milk - 120 Calories - 4.5g Fat
  • 1% Milk - 100 Calories - 2.5g Fat
  • Skim Milk - 80 Calories - 0g Fat

Milk Allergy

If your child has a milk allergy and is truly allergic to milk proteins, then he shouldn't drink milk or eat other dairy products made with milk. These children can develop allergy symptoms, which can range from hives to more severe symptoms, such wheezing, vomiting, diarrhea, or even anaphylaxis.

Children with a true milk allergy should turn to non-dairy food sources to get enough calcium and vitamin D in their diet. They should also avoid all milk and diary products until they hopefully outgrow their milk allergy.

More common than a milk allergy is a lactose intolerance, in which kids can tolerate some milk products, but develop gas, diarrhea, abdominal pain, nausea, and bloating, but only if they drink too many milk products.

Unlike a milk allergy, in which the child has a problem with protein in the milk, even tiny amounts, children with a lactose intolerance have a problem digesting lactose, the sugar in milk. What is surprising to many parents, children with lactose intolerance can usually tolerate some milk products, the amount which depends on your child, so a child may only develop symptoms if he has an extra glass of milk, cheese pizza, or ice cream, etc., but is fine if he has milk with his cereal.
