I messed up with my kitten's food

I really messed up with my kitten's food I used to give him dry food for breakfast, wet for lunch and meat for dinner

For dinner I would give him things like salmon filet , chicken breast, beef steak etc Soon he started rejected dry and wet food so I would often Crack to his meows and give him meat so he doesn't go hungry.

Now he womt eat kitten food at all. He only wants to eat human food.

I know I really messed up. I didn't know I was supposed to avoid giving him human food.

What should I do to remedy this ? How can I get him to eat wet and dry food again?
