If it helps, I used to mix a small amount of peas INTO the cereal. Since she likes that, you might ease into other flavors by adding a teaspoon or two to her oatmeal first instead of straight:) Hope that information is helpful.
I still make that face!
Our little one loves her peas! They make her happy and silly! But then again, she loves broccoli and doesn't care for sweet fruit! Piper gets cuter everyday!!!
