What food is important to give 8 month old

My son is 8 months and still breastfed. I am doing 3 solid meals a day. I am doing purées and BLW mixed!

Some days I provide two different foods on his plate; other days I’ll just spoon food him a single purée and a purée mixed. I have been giving him veggies, fruit, toast, eggs, and little pastina noodles.

Is this okay? Should I be giving him meat? What foods are necessary and important for his development/health?

I hear people say milk is most important at this age, but then I see other mothers giving their babies all these foods for solids while talking about how they’re good for them, etc. I’m confused?
