Baby food

My 11 month old won’t eat. I make him 3 different meals a day & im lucky if he takes 3 bites. He will only eat fruit & yogurt. He will eat whatever we’re eating but only straight from our plates & it’s not always stuff I want him to have. What can I do??😩 do I continue offering him food & just hope he catches on? Or can I give him baby food so I know he is eating enough? I’m really concerned he won’t gain weight or maintain high weight when we cut out formula next month
