Baby purées

Yajaira

I have a question here… can I mix different fruits and vegetables for baby (7mo) purées? Example, I like to make him a mix of banana, berries, spinach, mango and baby cereal. Then lunch/dinner carrots, sweet potatoes, squash, chicken, tomato, bell peppers,… I know it might seems dumb but besides allergies concerns idk if there might be any other reason I shouldn’t do it that way??
