A four year old's land

My four year old has a make believe land, where he gets to make the rules. Its called China, you may think, you have heard about China. But let me assure you, you have only heard about real China, four year old make believe land China is nothing like the real China. In J's China they write English letters, but upside down, or side ways, or missing a tail, etc, (basically English letters he wrote wrong by mistake). For example a M becomes a W in J's China. J's China is a great excuse to make your mistakes wrong. In J's China's they speak Spanish. But it is nothing like the Spanish you have heard before, instead it sounds like gobby gook coming from a four year old mouth. So if you hear China or Spanish coming from my son's mouth, don't think he is talking about anything real or tangible, he is just taking about his pretend land where he gets to make the rules.
