Homemade Oat Cereal For Babies

Want to make baby oatmeal? Made with just oats, water and a little cinnamon, this homemade oat cereal for babies is ready in 15 minutes and is cheaper than store-bought!

Hi Friends!

Today I wanted to share how to make baby oatmeal. When my oldest was little, we used a mixed approach that involves some baby-led weaning and some spoon fed things like oatmeal. Baby oat cereal was definitely one of his favorites but I got tired of paying so much for oat cereal marketed specifically at babies so I decided to figure out my own baby oatmeal recipe. It’s not really a recipe since it’s basically just oats…and water…and a little cinnamon but I think it’s worth sharing because it’s SO easy.

How To Make Baby Oatmeal

Since oat cereal is basically made out of just oats, I figured it would be easy enough to make my own. Since I food prep every weekend anyway, why not add this to the mix and save a little money by avoiding pre-packaged baby cereal. I calculated it out and if I buy a 10-pound box of oats at Costco and make this myself it costs something like $0.08/serving vs. $0.55/serving for a packaged brand!

A Note About Oatmeal For Babies

One thing that’s important to remember is that a lot of parents use homemade baby oatmeal (or storebought) as a source of iron for babies. One of the best things you can do to help your babe absorb the iron in oats is pair their baby oat cereal with a source of vitamin C. This helps them absorb the iron, which is a critical nutrient. You can easily add vitamin C to baby oatmeal by topping it with fresh berries like berries like strawberries, mixing it with pureed  or mashed sweet potatoes or serving with a side of kiwi!

This recipe can easily be doubled or tripled to make a bigger batch.

Like I mentioned in the recipe, this will firm up into a semi-gelatinous mass once it cools and is stored in the fridge. I serve them thick to my kiddos but if you want to thin them out, feel free to add a little formula or breast milk.

I love exposing him to spices at such a young age so I add cinnamon when I make them. I also often mix in some fruit or veggies before serving. He loves them mixed with pears, applesauce or avocado!

One nutritional note: Store-bought infant cereal is typically fortified with iron, which is an important part of a baby’s diet. Formula is also typically fortified with iron and since my oldest was formula fed, I wasn’t concerned that he would be missing out on iron in his cereal. However, if your baby is exclusively breastfed and is 6 months of age or older, it’s important to make sure they are getting iron from other sources if you are giving them homemade cereal. The good news is there are plenty of other ways to add iron to your baby’s diet as they delve into the world of solid foods! If you’d like to alternate between homemade oat cereal for babies and storebought, one brand I really like is the Happy Family Organic Oats and Quinoa Baby Cereal. It comes fortified with iron as well as vitamin C to help absorption!
