I agree with tylersmommy, you need to prioritise milk over solid foods for a good while yet - one way to help this is to get dd to maintain her pre-solids quantity of milk until 9-10 months old, offering foods only as tastes, something to explore and experiment with (an Activity) rather than something to Eat - I often suggest that you keep milk as Eat and solid foods as an Activity in the EASY schedule, this helps milk to be given first, and solid foods shortly answer as an activity, still leaving enough time between that dd will be hungry for her next milk feed, which is what you want!
Milk contains absolutely everything that dd needs for healthy growth and development, so whether she actually swallows much solid food or not doesn't matter too much, as long as she gets to practice with it. It is easier for los to maintain their milk supply with a self-feeding approach, but as you are having success with spoon-feeding, I would just keep a close eye on dd's 'finished' cues, so that she doesn't swallow more than she wants/needs and not want her next milkfeed!
HTH a bit?
