I'm going to let my child laugh at a foreign name
Why do you want to let your child laugh at a foreign name?
Because the name varies from language to language. They think it sounds funny.
You shouldn't teach kids to laugh at inappropriate things. They should be taught to respect foreign culture and language.
All cultures and languages are different. I'm sure the kid will learn that there are thousands of different languages in the world.
That is great if they are learning, but laughing at or mocking a name is detrimental to them learning that.   Why not use the opportunity when they laugh at the sound to explain the culture behind the name so that they understand it better.
