How can I get baby off bottle now he's turning 1?

Ra

My son is 1 next week and has a bottle morning and night. I know it isn't a problem but babies don't really need bottles after they are 1 so I thought it's better trying to get rid of the bottle when he's younger rather than older. How did you about dropping the bottles? The problem is he doesn't drink well enough out of a sippy cup bye he maybe 1-3oz of water over the whole day.
