What do I do πŸ˜©πŸ§€

My one year old has started to throw all his food off his tray and only want cheese. Shredded cheese, grilled cheese, anything with cheese. He doesn't do this every meal but it's becoming really frequent. He's throwing everything to the floor and refusing to eat...but if I make a grilled cheese he will eat a ton.

Do I keep making him alternative meals with cheese if he doesn't eat or will that just make this all worse? Do I let him go hungry? I'm so nervous
