You can't go wrong with the classic peanut butter and banana flavor combo! This oatmeal baby cereal is perfect for your 6 month+ baby (once you've determined there is no peanut allergy).
Add all of the ingredients to a food processor and pulse until you reach your desired consistency. It can be thinned out with water, baby formula or breast milk if needed.
If your baby is ready for a chunkier constisency, mash the ingredients in a bowl with a fork instead.
