Can Babies Drink Oat Milk?

Written by: Kelly Donovan

Oat milk has plenty of health benefits. But as you transition your baby off of breastmilk, you may wonder whether or not it's safe for babies to drink oat milk?

According to the Centers for Disease Control and Prevention, children under one should not drink oat milk, as they do not meet a child’s daily nutritional needs. 

Although babies can have oat milk after 12 months, it does not contain the nutritional benefits of breast milk.

Babies will continue to need additional nutrients to maintain proper development and growth.

Read on to learn more about giving babies oat milk!  

Can Babies Drink Oat Milk?

According to the Centers for Disease Control and Prevention, children under 12 months should not be given any type of milk other than breast milk. 

This includes cow's milk, oat milk, soy milk, cashew milk, almond milk, etc. 

Other types of milk do not contain the nutritional requirements needed by your child to maintain proper development and growth. 

Although children can start having oat milk after one, it still isn’t exactly recommended. 

Many doctors recommend children old enough to stop drinking breast milk or formula should be introduced to whole milk, as it has the protein, fat, vitamin D, and calcium children need to grow. 

Unfortunately, oat milk does not have adequate amounts of these nutrients.

Is Oat Milk Good For Babies?

Although children can consume oat milk after 12 months, it’s not recommended to be a staple in their diet. 

Oat milk does not provide many nutritional benefits to babies and toddlers, as it does not contain enough protein, fat, calcium, or vitamin D to satisfy a child’s dietary needs. 

If you want to give your one year old oat milk, doing it sparingly. And make sure they're getting their nutrients elsewhere.

Can Babies Drink Oat Milk Instead of Cow’s Milk?

Babies should not drink oat milk as a complete alternative to cow's milk, as babies have nutritional needs that oat milk simply cannot provide them. 

While cow’s milk provides fat, protein, calcium, and Vitamin D, all of which are essential to the growth and development of children, oat milk lacks almost all of those. 

When it comes to the nutritional differences between the two kinds of milk, it's hard for any type of milk to compete with cow's milk (at least naturally). 

If your baby has a milk allergy and must avoid dairy, most pediatricians recommend meeting with them for advice.

Benefits Of Oat Milk For Babies And Toddlers

Although oat milk should not be given to babies and toddlers as a dairy substitute, you can make an argument that it’s one of the best dairy alternatives. 

So what are some of the benefits of oat milk for babies and toddlers? 

Easily Digestible

Oats are often recommended for toddlers, as they are easily digestible and allow them to feel full longer.

The same benefits go for oat milk!

Oat milk has a high amount of vitamins and minerals compared to many dairy substitutes and contains many necessary antioxidants such as magnesium, selenium, iron, and more.

Finally, oat milk can be high in fiber, which is essential for a healthy digestive system.

Good Source Of Calcium

Many oat milk brands are often fortified and enriched with calcium.

Although it won’t be as much as dairy milk, it’s enough to keep your baby and toddler’s bones healthy and strong.

Additionally, the amount of calcium many oat milk brands contain is enough to help your toddler’s overall nerve and muscle functions and cardiovascular health.

Strengthens Bones and Teeth

Although oat milk isn’t as nutritionally dense as dairy milk, it contains more calcium than many other milk alternatives, like almond and soy milk.

Because of this, it can boost your baby or toddler’s skeletal tissue development and help aid in the development of their teeth and nails.

Strengthens Immune System

Since oat milk is made from fibers and proteins, it helps strengthen immunity and aids in cellular development.

These are incredibly important in the early stages of development, making oat milk an excellent milk alternative to choose for your baby or toddler (after turning one).

Heart Health

Although your child needs healthy fats, the fat content in dairy milk can sometimes be incredibly high, especially when your child is likely getting it from other sources.

Consuming a large amount of fatty dairy milk on top of other fats can clog your child’s heart at an early age, which can lead to more issues down the line as they age.

Oat milk can provide a great substitute that can help keep your child’s heart healthy.

How Much Oat Milk Can Babies Drink?

Babies under 12 months old should not drink oat milk at all. Until that time, babies require breast milk or formula to get the essential nutrients for growth and development as an infant. 

After they are over the age of one, you can gradually introduce babies to oat milk as you watch for any allergies they may have. 

Even so, you probably still don't want to give babies or toddlers more than a serving of oat milk per day.

That said, oat milk is great for recipes and the occasional drink. 

Best Oat Milk For Babies

Finding oat milk suitable for your baby can be tricky.

We recommend only giving your baby oat milk that contains two ingredients, organic oats and water. 

Non-organic oat milk can use oats that have been sprayed with weed killer and pesticides, which you should avoid whenever possible. 

Here are the best oat milk brands for children:

How To Introduce Oat Milk Into Your Baby’s Diet

If you’re looking to introduce oat milk into your baby’s diet safely, you should first meet with your pediatrician for advice.

Each child is different, and each will have different nutritional needs. 

Many pediatricians state that children over 12 months can be given oat milk in some situations, such as being allergic to dairy milk.

You should still make this decision with the help of a medical provider. 

As discussed, oat milk does not have dairy milk's nutrition.

Children need a certain amount of nutrients to ensure their growth and development stay on track.

So it’s essential to make sure your child is getting nutrients elsewhere if you’re giving them oat milk instead of regular milk.  

Always consult a pediatrician before changing your child’s diet, as they can point you in the right direction and provide you with great information. 

Potential Side Effects Of Oat Milk For Babies

Although oat milk is a great dairy alternative, you may find that your baby can have a few side effects when introduced to oat milk. 

Here are some of the side effects to watch out for:

Upset Stomach

Some babies don’t do well with consuming foods that may be richer in fiber, such as oat milk.

Because of reflux, this can lead to your baby getting an upset stomach.

It's always better to introduce oat milk to your child slowly. 


Although most people aren't allergic to oats, some are! 

Make sure to look for any signs of an oat allergy when introducing your baby to oat milk.

Gluten Sensitivity

Although the oats used for oat milk are gluten-free, cross-contamination can sometimes occur in the processing stage.

If your baby has a gluten intolerance, you may find that oat milk is not for them.


Since oat milk contains both insoluble and soluble fiber, it can cause bowel movements in the body.

If your baby consumes too much oat milk, you may find they will have diarrhea.

Heavy in Carbs

Since oat milk is made from whole grains, it is considered a carb-rich food and can be hard to digest.

Additionally, your baby may not need that many carbs in their diet, as they are likely getting it from other places as well.

If you are looking to add oat milk to your baby’s diet, you should consult their physician before making any big decisions, as they can likely give you a nutrition plan that will account for the amount of carbs oat milk contains.
