My 6.5mo nurses on demand and occasionally tastes solids such as a slice of avocado, banana, broccoli... My girl is little too, so I want to make sure she gets all the milk she wants.

Babies don't need anything else before around a year, regardless of weight. Solids are just for fun, practice, and learning! There is no food that has a better proportion of nutrients for your baby at her current age than your current milk.
