Purées and BLW

I’ve been feeding my 7 month old purées and she eats about 8-10 tablespoons of food 4 times a day. And she loves it. But I’m interested in starting some BLW feeding techniques to help my LO learn to feed herself. My only concern is that she’s eating so much and I don’t want her to be hungry. I also don’t want her to start drinking more milk than she already does now to satisfy herself...I want her nutrients to be coming more and more from foods. I know the BLW community is taught that “food is fun before one” but I honestly don’t believe this. Food is definitely more than just fun for her being a source of nutrients. I don’t know how to ask this....but have any other purée moms started BLW techniques and how?
