Too much screen time

How do/did you reduce screen time. My son was sick & getting 4 premolars so we let him have more TV time. Now he constantly wants the TV on or he's grabbing remotes. He's 20 months. He's getting his canines in & again getting extra crabby.

He's also giving us trouble with bedtime. He's running himself ragged before he's willing to lay down. I've been trying to wean him which has been complicating things

He loves his trucks, mega blocks, stuffed animals. He likes books & puzzles enough.
