6 month old Diet

My son is breast fed and he eats fruit in the morning and a veggie At night I make homemade baby food the jars I have ate 2 oz and he normally can eat a whole jar but lately he has been wanting more and this morning he ate a whole banana. I don't want to over or under feed by baby how many oz if baby food does your 6 month old eat and if you mash up bananas how much of it does your baby eat I'm so surprised he ate that much but I am a first time mom so I'm not to sure what's normal or what is recommended. Please let me know l!!! Oh he also eats from my breast every 3-4 hours. Thanks for reading 😅
