Feeding baby table adult food

At what age did you start letting your baby try real food? My baby isn’t crazy about baby food although i still try. Maybe I should buy better spoons or should try a high chair. He’s 6 months old and I feed him while he sits in his bumbo chair. I can’t eat or drink anything without him leaning towards it trying to grab it and making noises. He LOVES real food but I know he’s too young. He has no teeth yet. I let him try a good bit of stuff although it’s usually mashed or just a lick or juice from fruit or something. I’m wondering if I’m going to hurt his stomach by doing this too early.
