How is the Trinity explained to children?

Orthodox Jew here, trying to get a grasp on what your average Christian believes about the nature of God.

Honestly doing my best to research and understand the various explanations, but (like a good Jew), I'm finding it very difficult to even wrap my head around.

It's extremely difficult to find a clear explanation that doesn't use words like "hypostatic union of a truine godhead."

So I'm curious, what is the EITMLI5 version of the Trinity?

I imagine young toddlers are told something like "There is one God, He created everything, He loves you..." then what?
