How to turn off Monster Spawn on Minecraft Xbox 360 Edition?

I have Minecraft Xbox 360 Edition. I love it and I'm trying to build something amazing, but the monsters spawning everywhere make it difficult. There's probably no way to turn off the monsters or maybe have it be day time the whole time, but if there's a way please tell me. It's very annoying and getting in the way.

Go back to the start menu and go to the options.
In there you should find a category named Difficulty. Set it to Peaceful. It will only spawn pigs, cows etc… But none of the mobs that will hurt you. By turning this mode on, it will also give you full hunger all the time.

Just put it on peaceful and there will be no mobs
