Iterate through child entities

I'm trying to make functions to modify grids of entities that are child of a mesh entity. I would like to know if I could iterate through the child entities. if so, would FindChild help me go through all the child entities. or how would you go about doing so?

I found this thread, but I have my doubt on the need for having complex recursive trickery just to pass through 1 level of child entities.

Maybe you could use the CountChildren command with the GetChild command ? Else, try Beakers NextChild function:
