You can but I use a kitchen aid food chopper. It has the option to purée

@mommaofjais, that’s is awesome. Do you use just a regular blender to purée them?

I do. We’ve done bananas, avocados and peas. You don’t have to cook the bananas and avocados. We just purée those and add a little of formula or water to it. I bought frozen organic peas and cook and then purée those. I plan to do the same thing with butternut squash next week. Make sure you wait 3-5 days in between introducing new foods to rule out allergies
