How much solids 9 month old? Am I doing this right?

How many Oz/servings do you give your 9 month old of solids per meal? How many meals? I’m worried I’m not giving my baby enough solids...but I also don’t want to over do it! I still breastfeed as well.

I hear all these people saying “food before one is just for fun!” Then I hear other people saying that baby needs 3 meals a day 8oz of fruits or veggies, 2 Oz of cereals, 2 Oz of meats, babies plate at each meal must have high calorie food, high iron, and fruit/veggie.

I’m just very confused and honestly stressed about this.
