Baby only wants fruit 😭

So I’m having a problem. My baby will absolutely destroy some apple sauce, peaches, and pears...but he won’t eat much else anymore. 😭 I’m a ftm so I’m kinda overwhelmed. He is 8 months, and he can’t just eat those things. He gagged when I offered him peas today, and he never did that before. Please help. How do I get my baby to eat other things.
